sometimes yes, sometimes no. Inbetween I loaded the .stl by using stl only and it worked for on or two prints but I am still not happy. Thank you very much for your support.

Same "intermittent" problem here: Cura 4.8.0 and Big Sur 11.0.1 (on latest MBP16 2020). After importing the different stl files on plate, the only way to select them is via the object panel (very uncomfortable... ok as a precise option, but usually far better to click on an object to select it), and as soon as I try a movement or transformation, they get unselected... I need information which Cura version works peerfect and how to install it. Big sure allows to install Cura 4.8 only. I get crazy, I got a new Ultimaker 3 and cannot print with it. I need to turn the objects. Is there someone who solved the problem. Thanks for help and I wish all a merry X-mas anyway.
