Can my rater lie about the number of soldiers that he/she rates in my NCOER?

Good Afternoon, I’m inquiring about the NCOER process. I was on ADOS with my Battalion S1 for a year & 7 months. My rater who is an E7 was not honest about the number of soldiers that she currently rates. She stated that she currently rates 4 NCOs. However, I am the only NCO that she rates. This information is also reflected on the BN rating scheme. Also, in the overall performance section she first stated “4 out of 4 NCOs that I served with in my 12 years in the Army”. Then a month later she unsigned the NCOER, after it was kick back, & she changed it to “3 out of 4 NCOs that I over seen in my 12 years of service with the Army”. When I asked her about it she didn’t respond so I reached out to the Senior rater. She was upset that I mentioned her grammar mistakes to the senior rater then added a second comment to my Overall performance section “needs to develop professional environment maturity”. She also only had one bullet in the presence section. She was asked to remove some inaccurate comments by the command and never added new comments to the presence section. She recently closed out my NCOER without my signature and stated “refused to sign”. However, I was never asked to review the final copy. I did not refuse the NCOER because I was never informed it was complete. The NCOER still has some grammar mistakes (Over seen should be one word & “professional environment maturity“ doesn’t make sense together) so it will be kicked back. My question is: Can my rater just lie about the number of soldiers that she currently rates? Can she change the context to over seen if she only served with other NCOs? Can my rater close out my NCOER without me viewing the final draft? The NCOER was due in September.
