Date Drop Down Not Working in Big Sur

Thank you for letting us know your experience after updating to macOS, @gh99.

To resolve this, let’s run the Verify and rebuild tools. The Verify Data will identify any data issues within your company file. Then, the Rebuild tool will self-resolve it. Check the steps below:

Verify data:

1. Go to File, then Utilities and choose Verify Data.

If it will detect an error, proceed and Rebuild your data:

1. Go back to File menu and then Utilities and select Rebuild Data.
2. Choose OK if you’ll receive a message to back-up your company file.
3. After creating the back-up file, the Rebuild Data utility will run automatically.
4. Click OK when you get the message Rebuild has completed.

We are aware of this - we've been working on Big Sur issues throughout its long beta cycle. It takes time to validate a release and Apple didn't give much notice.
