New Version Causing Problems

Ever since I updated to the new version (Version: 2.4.3) I have had significant problems.
– The search icon in the navigation is offset from the rest of the menu items.
– The sticky header only works if 1) I’m not on the homepage (I have the special header style enabled on the homepage) and 2) I don’t have the top header enabled.
– If I have the top header on, the top header covers the entire screen.

Please let me know what I can do to fix this. I can also revert to the last version of Highend since this all seemed to work with that version. Please let me know how to do this.

Thank you,
