Hi,
Your site header was built with the Penci Header Builder, so please go to dashboard → Header Builder: click "Edit with the Penci Header Builder" on the current head layout, and removed all elements on the Sticky Header area.
On the mobile, please select each row, then select "No" at the "Sticky This Row on Scroll Down?".
Regards,
PenciDesign.
