Fighting with "Style attribute" in grid

Hello there,

I am evaluating Pinegrow, which seems to offer some great features (I am coming from Dreamweaver and VS Code).

I made a grid with named cells. To make them into named areas I need to use the “Style attribute” label.

I managed to see this thing exactly once (in the first row of cells) of my grid.

Trying to use it again in other cells all I get is this:

27

I’d appreciate some insight into the handling of the style attribute label.

Thanks a lot.
