Hornet IFA fail

[Supernova-III]

After switching INS alignment to IFA (when the alignment process is finished), information about alignment usually disappears from AMPCD. But sometimes it doesn't, and even more, it starts counting seconds. In my case it occasionally happens in the mission I've created recently, but not every time... The date in the mission is set to Jun 2020. trk attached. Please help me, it annoys me from time to time in different missions.

Are you starting in a shelter?  If you don't have visibility to the sky for the GPS it will show IFA RDR until shortly after you leave shelter and it can get GPS signal.
