When I complete or do a question, the number until level up turns into a bigger number on the bit that says xp until level up when number should be decreasing.
It's a minor UI readability issue I've actually mentioned before in the private group. For example, this looks like I need 12 XP to reach level 32, but it's actually 88 XP :D
It's just the "XP until next level" wording making it seem like it should go down from 100 and tick over at 0, not start from 0 and tick over at 100.
PS: Happy to see I'm not the only one who got confused by the wording there
