Character slots limit bugged

Everytime i buy chaaracter slot in shop it eat 2x limit while giving one ticket only, it will be problematic because in KR there are 24 slots for characters atm and with this rate i already can’t buy enough tickets to get all slots covered, as i got 9 slots left which is like 4 slots in reality it that continues.
I noticed is sadly only today, yesterday was 13 slots and i bought one and today was 11 i bought one to have 12 overall and now its 9 left.

I talked with people on diffrent LA streams and it seems not only me got that problem.
