Hi @bethatgirly ,
It looks like a glitch.
Have you tried to update the app or check if the same issue happens on the desktop version?
If it still persists, aside from being patient, it could be a good idea to contact support about it. They are probably aware and working on the issue.
Pinterest has been working on different features and glitches like this happen.
Sometimes this problem happens to me and I find that if I simply completely exit the app, shut the app down, and then go back in it is fixed. (So when you swipe up out of the app go slower than usual and swipe to so that the app is completely turned off from use if that makes sense.) It works to get rid of a lot of little glitches like this
