Hi Tolis,

Thanks for your patience.

1. Overlap header

I double checked and the issue has been resolved (without using Custom Layout) https://prnt.sc/6JY5x4Yq9fHO

2. Homepage

Homepage is using Custom Header https://prnt.sc/cS4n6pQtF1oA, you can make it as Default header and set it to None.

Regards,
