Help with second master page

I am not really sure if the forum is used for support or email or what so I am posting here as well as sending support email. When I add a second master page, the styling for the header gets messed up, not only for the new page, but also the previous header on the original master page.

Before Header -

After new master page has been applied -, this is the same page as above

New page page header -, same spacing issue and but also the home menu is messed up.

html versions

Thank you for anyones help and I hope you are all staying safe.
