How can this be fix?

i used it 3 days ago and for me everything worked correctly

But what is weird is that I have 2 Xbox account an on my main one I have a problem maxing out the stats. But on my other account that I hardly use I don’t have a problem maxing them out. So I would say that I am a little confused as of y?
