- Could you please answer a few additional questions:
Since when does this problem exist?
Was the problem always like this, or did it arise after an update or a new program installation?
Does the problem only exist on your computer or on several computers?
Does the problem only exist with one document or also with a newly created document?
Where is the document? ... hard drive, OneDrive, network, Sharepoint, cloud, ect.
Do you have several versions of Office on your PC?
Additional actions you could do:
Install or update the next / latest version of Office applications.
Also, check for the latest upgrades of your operating system.
If the document is not on your PC, create a new one on your local PC and see if it behaves exactly the same.
Thank you again for your understanding and patience

I know I don't know anything (Socrates)The problem has now existed for a few weeks and happens on all our computers. There were no newly installed programs, and as this only affects Excel online it should not be affected by those anyway. It works on the desktop app, but most of our workers don't have access to that. There have been no updates I am aware off. The problem only exists with this particular spreadsheet as far as I know, and it is stored on Sharepoint Online. The spreadsheet is mixed manually and conditionally formatted coloured. We are always using Edge as our browser, but the problem shows up in Chrome as well.
Any help would be greatly appreciated.
