Can't enable comments for Portfolio

Hi. I noticed the comments are not showing up for my portfolio items, even though I enabled them on the page (in Discussion options).

After researching this, I discovered this is because I am using the Avia Layout Builder on these portfolio pages (if I don’t use it, the comments will show up).

I tried adding this code to the functions.php file:

add_filter(‘comments_open’, function() {
return true;
}, 9999);

But the comments are still not visible. Is there something else I’m missing? Thanks for your help.
