**Your software**  
My Mautic version is: 2.16.1  
My PHP version is: 7.2

**Your problem/question**  
My problem is: When I add HTML with CSS classes to the DWC they get replaced with ‘fr-original-class’ and therefore the style is not applied.

## These errors are showing in the log:

Steps I have tried to fix the problem:

Original HTML

Resulting HTML

Can I somehow keep the classes?

Thanks

I have the same issue, unsure how to keep original formatting and it’s very annoying.
