How to remove boxes outlines ?

Hi! I'm new using Anytype, and when using the Mac Desktop app (version 0.56.1), all the boxes outlines are showing (see pic), as well as a purple bloc for empty space. Is there anyway to remove them? Or is it by default present? I don't have those when using the Android app...
