malfunction in edit

Hello everyone or Support..?

I am using Capture One Pro 20. 

For a while the program has been teasing me when I'm inside the Exposure and high dynamic range adjustments. Incredibly many times I can't get the sliders to move in for example the contrast, saturation or black settings. It's a bit different from time to time. Only if I enter a value in the slider window and press enter, I can get the slider to move and the effect can be seen on my image I am editing. It's so annoying

Can you help me there?

I am using Mac Ventura operating system

Best regards Peter
