Edit/delete Elementor boxes in edit screen

Hi, I am working on a website with a collegue and something strange is occurring. I am working an a Chromebook and able to edit or delete any Elementor box in the edit screen.

My collegue, working on a fancy Mac, does not get any options if she clicks the pencil-edit icon.

We are logged in under the same username, so the difference is probably in the machine we use. Does anyone have a bright idea (other then selling her Mac 😉 )

Thanks for any idea!
