Category Image missing on main category page but shows up when filtered

I have a category image assigned to a page, but it shows up only as gray color (default color) on the main category page but when I click the filter on the dropdown list, I see that the background image shows up. I’ve cleared cache, cleared wp rocket/opcache and no luck.

I can see the div element for background only exists when I select filter. any pointers?

Turns out it was wp-rocket, it really doesn’t like this theme. Disabled most of it and looking at the recommended one
