Although I don't have any solution or hypothesis for your problem, I did notice something in one of our matches last weekend. The FMS messed up the hot goals (
As seen here).
None were hot for the first ~5 seconds, then the left was hot for the last ~5 seconds. But right as the bell rings for teleop to start, the right turns yellow, indicating that it is hot. If you look to the left of the frame, you can tell (watch a few times) that the same thing happened for the blue alliance.
