Can tick contradicting tickboxes, and error message is unclear

[alessandrofelder]

Describe the bug
Error message unclear and I can tick both "all" and e.g. "funcimg" (which I think shouldn't be possible). If I then hit "transfer" I get an error, which I don't understand... which options does "these" refer to?

Expected behaviour

• If I tick e.g. "funcimg", "all" should get deselected.
• It should be clear what "these options" refer to in the error message
