Unable to adjust columns number in GT3 Gallery grid

Hello guys, I’m creating post today and when I create new gallery, ad image, set columns to 1 and confirm, it looks fine in the page while editing, but when I save and go Preview or refresh the page, the settings is not saved. Screen recording for better understanding here. I see you did update few hours back, none of my others plugins did, so it has to be issue here. Can you please look at it?
