Hello,

First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :).

I saw the screenshot you attached.

Please make sure that you have set both the addresses same as mentioned in the following link:

Then Go to WoodMart >> CSS Generator >> Generate CSS file.

Then try making changes to the headers.

Then clear cache and check back.

Best Regards
