This is a known issue.
For now, the way to work around it is to change your game window size (Settings->Options->Graphics->Resolution)

We're trying.

The skill's description explicitly states that it can't exceed the Spirit Savior daily cap.

Your MVP Special rank is based on your spending in the current month and the previous two months.
On the 1st of every month, the system "forgets" everything you spent two months ago, all at once.
So, for example, if you spend a million dollars' worth of NX in January, and nothing after, then you'll be MVP Red in January, February, and March. But on the 1st of April you will drop back to Bronze IV, because everything you spent in January stops counting at that point.

In my personal opinion, the only healthy way to treat MVP is to ignore it. Buy only what you want (and can afford) from the Cash Shop. If it happens to get you some MVP rewards some months, great. If it doesn't, oh well. Don't spend just because the game tells you that you "have to" in order to keep or increase your MVP rank.
