Majestic Metrics Drops

I have been purchasing PBN and pointing them to my money site. I have been documenting DA and TF using Moz for DA and TF from Majestic, but I discovered my TF dropped from 10 to 1 on my money site and 9 to 3 on one of my PBN sites. My money site went up one Point on the DA and the PBN stayed the same.

I measured another PBN site and noticed they also lost TF but not DA. What could be causing this and how do fix this?
