Also has the same problem, unfortunately, I have tried restarting and opening up old case files and all have the same behaviour. Tried turning off the computer and retrying if is was some settings but to no luck.
I create a new model and i only see the step subtree instead of the full subtree on other models. This is frustrating as can't quickly change workflow. I know I can use the top bar to get to the correct workbench. Is there any way to solve this issue?
