Problem with Excel Files

We have the problem on several Android devices that Excel tables do not open in the cloud. They will open on the device. Other files (*.doc or *.ppt) are opened in the cloud. Clearing cache and reinstalling are unsuccessful. Does anyone have an idea?

Documents-App: 8.2.3
Android: 9 and 12
The problem only occurs with Excel files in the cloud. Excel files on the device will open.
