Show folder content when using large icons

I am using windows 10, and ‘autocad & solidworks’ . Once I installed the nextcloud desktop application, it modified all the folders that I selected to sync.

Now the problem is that in order to find out the content to work on, instead of just opening the folder, I have to open each file, I have tried uninstalling, reinstalling ( without the explore integration).

I have marked the problem files in red to show an example

Note: I tried to upload it here, but it kept failing.
