Mobile Layout for Woo Recent Products showing “blank” areas

I’m not sure what happened to my previous topic so my apologies if it appears twice in the forum.

I have my mobile layout currently set to show two products per row using some custom CSS. The issue I’m having is in mobile layout sometimes there would be a blank space as if a product is missing or not being shown. I cannot figure out what is causing this issue. Here is what I have tried:

1. Removed all custom CSS (except for the one that allows for 2 products per row). This does not solve the problem.
2. I switched themes to Twenty Twenty-Two with the settings in #1. I reloaded the site 10x. I don’t appear to have the issue anymore. I am now assuming that it might be a Highend issue. I switch back to Highend child theme. The issue reappears.
3. I reload the site several more times on mobile. The issue disappears and reappears every so often. It is intermittent and I’m not sure what is causing it. It seems to only happen on my main page and not the product category pages, although that remains to be seen. For now, I have not noticed anything yet.

Here is some information about my main page product listing setup:

– I am using WPBakery Page Builder
– I have created a row. Inside this row is Woo Recent Products. 12 products per page, 6 products per row, order by random, sort order descending.

Can you please tell me what is causing this issue and how I can fix it?
