Hello,
Navigate >> Theme Settings >> Product Archive >> Shop Filters >> there you can select the Content Type.
There are two options for its Content Type (Widgets or HTML Block): https://ibb.co/hYrJnnH
If you select the Widgets > then you need to go to Dashboard >> Appearance >> Widgets >> there you can add the widgets under the Shop Filters area: https://ibb.co/wBXGM4Q
Or the second way is the HTML Block. You can go to Dashboard >> HTML Blocks >> create a Block with Page Builder active on your Site >> and then use that Block as the Filters area by selecting that Block under the Dashboard >> Theme Settings >> Product Archive >> Shop Filters.
Here is the documentation: https://xtemos.com/docs-topic/how-to-create-filters-form/
If the issue still remains, please deactivate all the 3rd party plugins and activate only theme-required plugins on the site and then check the issue. I am sure your issue will be solved. Then activate the 3rd party plugins one by one and check which plugin is creating the issue for you.
If the issue still remains, share the WP login details so I can further check on your site and give you a possible solution.
Best Regards,
