The USA also had similar issues with composites in the Zumwalt class and the last ship is supposed to have the deckhouse built out of steel instead.

The composite super structure of the first two Zimwalt class is actually lighter weight then the steel. But it's more expensive. The weight savings reported has more to do with how the sensors are mounted then the actual deck house. The steel is however favored for cost and durability.

Does this (what you stated in your post) have any direct correlation with the ship's center of gravity, and it's ability to perform hard combat maneuvers, and/or to be able to withstand strong weather and waves? Because as I understand it (I have limited nautical knowledge) a ship must have balanced weight distribution with regards to its construction. I would appreciate your input on this.

Absolutely. A heavier structure located anywhere on a ship or any object in general will shift the center of gravity and in the case of a ship unless counted by reduction elsewhere alter the waterline.
In the case of naval ships tall heavy super structures make the ship more likely to roll over.
Take the Uss Long Beach for example. Just the other week I read a interview with on of her former Crew who mentioned that the crew got very nervous if the ship started listing anywhere near 11 degrees. Now long Beach was a Nuclear powered cruiser among her unique aspects was her deck house which has the same phased array radars as the Enterprise CVN64 It also sat very tall the Bridge crews could look down onto the decks of carriers. When the ship did list to 10degrees it took a long time to return to normal because that heavy weight and center of gravity wanted to keep moving into capsize.

Removing weight from the bottom won't help matters as it would just make it more top heavy and adding weight to the bottom would help to a point but it makes the ship sit lower in the water and that makes it more risky in high waves.

I didn't notice the jagged nozzles till you reminded me!

That ship always seemed kinda top heavy to me. I mean there is nothing wrong with their existing ship designs like the Steregushchiy-class corvette. So WTF?

There are lots of issues with Steregushchiy class, but it is not the main point.
Basic Steregushchiy design is 17 years old at this point, it needs a replacement anyways.
And 20386 isn't just a replacement, consider her a new ship altogether.

How old is the basic Arleigh Burke design to begin with? If it ain't broken you don't need to fix it. Granted that corvette needed weapon systems and electronics upgrades. Those happened with the Gremyashchiy-class corvettes which use the same basic hull design.

And Steregushchiy is 100% broken.
It is too large, too complex and too expensive for a coastal combatant.
Russia can't build enough of them at this rate.
20386 fixes it in a very straightforward way: it isn't a coastal combatant anymore. Building rates of 20380/5 are pitinful for coastal combatants, but for frigates they are barely acceptable.

Burke was a visionary design, supported by a very special geopolitical landscape and desire to save money, yet gain as many independent combatants as possible.
Steregushchiy doesn't fit this picture at all. Underdeveloped frigate without a f_cking kitchen, but with area defence AA instead. Especially new ones, with their incredibly expensive ESA masts.
It is just too much of a waste for what ultimately constitutes an 056a job.
