[Counselor says IU gets removed once VRE is granted]

Howdy yall. I am so confused right now. I am 100% TDIU and I had a meeting with the counselor today and he told me that as soon as they grant my VRE that I will lose my IU. I've searched high and low for threads here and reddit and just the internet in general and I cannot find anyone saying that you will immediately lose your IU by being granted VRE. I totally understand losing it after getting back to work, but losing it just to go to training seems odd. I asked if there was a CFR and he mentioned looking into it.

Any links to this regulation? I'm at a complete loss for words. I was blindsided by this, on my birthday no less.
