Background cell color not showing in moddeler (document template)

I’m stylizing multiple tables in a document template. When using the app, and generating the report everything is fine. But when I work in the modeler the changes of background color are not visible, text color is. So when I use white for text, I cannot see the contents of the tablet. This is annoying and makes work a lot harder.   Is this a bug or am I missing something?

Probably a bug of the design mode. It's pretty young.

Might want to make it reproducable and report it to
