Players not ranking up

Question

I have ranked up my GK up 3 times. Now when I go to rank him up it takes away Mascherand, but never ranks up my GK. I’ve lost 4 Mascherand. Trying to get it to work. So far I’ve only had problems with my GK. Everyone else seems to rank up with no issues.

Each level requires different number of Mascherano. Always use 100% success.
