"Definitions" and "Calculations" dialogs cannot be closed

[marine_engineer]

I'm new to Robot and encountered a problem which couldn't fix it. I clikced on Design>Design Steel Members. Then two dialogs opened, "Definitions" and "Calculations". But those two are non closable and and the close button is disabled (see below image). How can I fix this issue?

Thanks for your time.
