I see what you mean, @dezsirazvan
I replicated the issue using this demo https://jsfiddle.net/zfgw30m1/
And it seems that the number of fixed columns equally requires more clicks than just one. For example, in this demo there are some checkboxes that get checked after 2 clicks, and some of them need 6 clicks. I got this result testing the demo on Chrome 105 on macOS Monterey. Does it work the same for you?
