Issue being the disputed land lies between the Indian Camp at Gogra PP17A and Chinese Camp 15 km away. So I don't think the Indian camp at PP17 A is specifically the problem but rather the area adjacent to it.
Seems like whatever be the LAC , to have India specifically note PP17A as a problem zone hints at what could've conspired.
Two possibilities :
1. If the LAC is as Mr
@twineedle suggests then that means forward deployments of Chinese troops are coming 15 km from the Chinese camp. Very risky even with Artillery support. Satellite images that Mr twineedle quotes also show that both camps are 15 km apart.
2. If the LAC is as per Ajai Shukla, then the presence of Chinese camps and Artillery would be nearby / even on the PP19 ( if it exits). We can then see how that is a problem and why India would want China to remove them.

From the article published on July 10, 2020 by Ajai shukla
The basis of negotiations, which is a simultaneous withdrawal of one km by both sides, is disadvantageous to the Indian side, because the Chinese have already intruded 2-4 km into Indian-claimed territory. Consequently the entire buffer zone would be set up on Indian territory. Yet, the Chinese are refusing to concede even this.
Anticipating the need to back up their intruding troops in the Gogra Post area, a large number of PLA troops have concentrated on the Chinese side of the LAC across from India’s PP-18, 19, 20, 21, 22 and 23, which is east of Gogra Post. Chinese artillery guns have been observed deployed across the LAC from PP-19.
Note : No other Indian media or source is providing as detailed a representation as the above. Whil they all agree and quote the Indian government on issues at PP17A general region, they don't explore further.
@ougoah You are right that both countries dispute the region.
