20.02 Layout Font Colors not loaded when loading Model

Hello, we work with very colorful models in Oracle Designer for 25 years now.

Beeing time to move forward we are trying out the SQL Developer Data Modeler.

I can live with the ER-Diagrams not beeing importet, though it hurts a bit with a 150 Entity-Diagram.

What I can not live with is:

When I format an entity in the logical model and change the background and therefore the font colors, save

and close the model, the font colors are all back to default when I reopen it. Rendering it to completely

non-readable with a dark background.

I took a look into the xml files and the font color information seems to be present, so its "only" the loading

process that dismisses those values.

Is this problem already known ? Will there come an update?

Oh, btw, using classification types could be a way out of this problem, if only there weren't so many different

kinds of entities/tables.

Best regards,
