TV weapons point lock issue

This has been an issue for a while and i am not sure if/when it will be fixed. Or if there is something im doing wrong.

Basically when i do a point lock the lock will constantly jump between the area i locked and another point usually like 100-200m below that (1 second intervals). This causes issues since i have to time the drop so that the lock is on the correct point and not the “fake” point.

What is this exactly? Bug or limit with TV guidance?
