Issues with the agm-65?

Is anyone else having issues with the agm-65s recently? For some reason, all day I have been having trouble getting them to lock onto tanks. I know they have a min distance before they can actually lock onto tanks instead of the ground but even under 4km, they will lock the ground in front of the tanks. Been having similar issues with the gbu’s as well.
Oddly enough, the kh-29t and the kab500kr have been performing mostly as normal.
