Dropdown lists don't work

Has anyone had a similar problem - Luban does not select an option from the drop-down lists - and knows how to solve it?
Reinstalling didn’t help.
Where can I find the previous version?

I probably have the same issue, can’t set model structure to Vase or back to Normal because of this issue.

Was searching for the best settings for my print and was finetuning it every print. So I don’t want to make another profile because I have to start over with my settings.

In the various settings? I sometimes have to click around between ‘basic’, ‘advanced’, ‘custom’ to be able to properly edit the settings.
