Hey Lise46. it sounds like you may have corrupted data. I recommend you run a verify on your file to ensure this isn't what's causing your issue. Here's our article on verifying your company file. The steps are pretty simple though so I'll list them below for you.
- Select File in the top left corner.
- Hover over Utilities
- Select Verify Data
If the verify happens to find any problems, you will be prompted to run a Rebuild. It may take a few minutes to finish running the rebuild but you should be good to go after that. Reach out to me if you have any other questions.
