Hello,
Sorry for the long delay in answering.
As I can see, you have changed some settings for headers and they look same in the Customizer and on frontend. Isn’t it? Was the problem solved? If not, please re-create the problem one more time, describe the desired result in more detail, provide FTP access also, and I will ask for assistance from our dev team side.
Waiting for your reply.
If you do not know how to create FTP contact with your hosting provider, they will help you.
Regards
