Minecraft Username change system won't let you change when there's 0 days left

Minecraft says that I still can't change my username despite 30 days passing. It says:

CHANGE PROFILE NAME

Oh no! You can only change your name every 30 days.

Your last name change was on 4/14/2020. You can change it again in 0 days.

It's probably an indexing begins at 0 bug. Just a little annoyance for me personally.
