Error code 38 on entering cash shop

I think I found a problem related to the situation, it applies to both of my characters that are stuck and doesn't apply to a few characters I tested that are okay.

Normally when you go over your EXP bar or your name, you can see your current exp/total exp + your id, channel respectively. On glitched characters, nothing pops up.

Does it apply to anyone else? Anyone can find some insight into this?

I see mine just fine. Might be a different related issue.
