Intellij Window in every desktop on MacOs Mojave

Hi there, 

I don't remember since when, but my Intellij window is now floating on the every desktop I opened on my MacOs. Basically, no matter which desktop you switch to (desktop 1 2 or 3) , Intellij window will always appear on the top of all other windows.

I tried restore the default setting and also tried reinstall Intellij, but it does not work:

Is there a way to keep one project window to be just inside one desktop?

Thanks,

Phil
