Can you take a look at these gerber files; DK Red says that the back solder mask is empty. How do I fix this?

Thank you for your inquiry.

I replicated this.

Did you intend for the bottom soldermask to be empty?

Your B_Mask.gbs file indeed doesn’t have any contents.

No, I need it to have something in it, otherwise it will not work on dk red
