MR 19 Test bug

[(XBOX)Operator9292]

I was doing my 3rd attempt at completing MR 19 test and I finally did it, I took the escort out and completed it, with it then coming up saying I'm now mr 19 and stuff, until when I exited the relay I saw that I was still mr 18 and and that the "NEXT" Mastery rank up was in 24hrs. This has become a pain and I hope this gets fixed because its really spoiled my mood😶. I didn't know until a few seconds and so didn't manage to get any evidence😫
