This has been reported as an ongoing issue in QuickBooks Online (QBO). A ticket (INV-39416) has been created and forwarded to our Product Engineers. They're now working to fix this odd behavior as soon as possible.
In the meantime, I highly suggest contacting our Support team so they can add your details to our notification list. This helps our Engineers determine the number of affected users. An email notification will be sent to you once this has been resolved. I'll also inform you here when we get the update as well.
Here's how to reach them:
