Deleting project collaboraters deletes the project?!?

[9ls1]

We have our own (self-hosted) QFieldCloud (ver. 0.26.4) installed on a server. Everything is working more or less very nicely.

However, today I wanted to remove project collaborators from a project from the QFieldCloud admin webpage (https://<server url>/admin/core/project).
I checked the box to the right of the collaborator and clicked Delete.
I was in a hurry, so I didn't read the information carefully and just clicked "Yes, I'm sure" (I knew which collaborators I wanted to remove and I had checked the correct boxes).
Too late I detected that I deleted the whole project from the cloud!
I only wanted to delete three collaborator (out of four).
And that's what I expected within the "Project collaborators"-tab (just an example from another project with only one collaborator). Here I would check the check box to the right:

When I want to delete the whole project, I have done it from the Projects list:

I know I can blame myself for not reading carefully enough, but I would suggest that it should be possible to only delete (remove) collaborators within the "Project collaborators"-tab. (Luckily, we have back-up routines of the self-hosted cloud, so I could retrieve the deleted project.)

P.t. how do I delete (only) collaborators from a project in QFieldCloud admin?

I've figured it out:
Check the Delete-check box(es) to the right for the collaborators you want to delete (remove) and click Save.

Reopen the project and the Project collaborators-tab, and you'll see the collaborator(s) are gone.
