Hi there!
Thanks for contacting us.
I have checked your site and found out you have added custom CSS for your page title section, but it's position is absolute and it's overlapping all of your contents, not only the bottom but also your topbar contents!
You can remove that custom CSS totally, or you can change your position to relative and/or adjust your top, height values there. I have attached a screenshot below:

If you remove that, your issue should be resolved.
Best Regards
