Bloques 3.4.2 Problem with color and titles

Update Blocsapp early today, and I am working on a new site.
I have encountered a very rare problem.

Attach a form inside a card, and everything is fine but at the time of changing the color name, apparently if it changes, but in the browser it still appears in black, and not white as shown in the configuration:

I did a test changing the color, but what changes is an h5 instead of the label, the image shows how I have selected the label, but what changes color is another part not selected!

This is a big problem

MR

@Norm Any ideas on this?
