Has anyone encountered any bugs that Claude wasn’t able to fix ?

Hello, Context is I vibe coded an app for our finance department for our team meetings. We have about 70 users across 5 teams. Basically you fill your input and then ur team has a global page showing everyone’s input together. But for some reason some peoples submissions don’t fully show so it shows as it wasn’t filled it even tho they did, then when they refresh it, it will show as if they didn’t change their status at all. I have tried to get Claude to review this and fix it but it just can’t seem to do it. Has anyone else run into things like this and how did you over come it ? Thank you
