Hi,

– The short description problem in the checkout process, I have checked and seen that the template on this has been changed by the Magesetup module, you can see the link below

So please try to edit again with the same file on this link.

– About the sticky menu issue, that seems to be solved, I have checked many times but have not seen any more. Please check again.

Thanks you,
