Dimik if you're using iOS devices you can log out of the app and log back in to hopefully fix it. (note that deleting and reinstalling will not fix the issue, as the issue is caused by downloading settings that were saved in iCloud. Logging out and back in is necessary.)
If the issue persists, please reach out to our Customer Care team from link below. Or through Twitter at OfferUp like goblin suggested in the post above if this option is available to you.
