Face detection named people groups merging

[kevinj33886992]

I have 45000 photos with a similar number of detected faces.  I have been tagging faces to the correct names and I have about 70 named people.  After doing this recreationally for about a year on occasion the face groups have begun spontaneously and seemingly randomly merging.  I will name an individual (changing the name suggested on the bottom of the box) and the software will shift to the group of named groups and highlight the name of an individual I was not naming and then suddenly a group will lose 90% of its photos to another person.  Obviously this is VERY annoying and has undone hours of work!  Help

I am assuming that you have gone through Lightroom Classic for this, and perhaps allowed it to upgrade?
