Hi Andy,
Welcome to Microsoft Community.
This issue may occur if there are multiple instances of Excel running. I will help you to end the multiple instances of Excel. Follow these steps to end multiple instance.
- Close all open instances of Excel.
- Right click on the taskbar.
- Choose Start Task Manager.
- Go to Process tab, search for Excel.exe process, right click and choose End Process Tree.
- Open Excel and check if the option is unchecked, if not uncheck it and check if the issue occurs.
