Hi,
I've checked your site, the problem is that one of your installs has enqueued the wrong JS file (related to the auto widget feature), so all the media settings on Elementor can't work correctly.

Please try to disable all plugins (excluding all the plugins that come with Soledad) then re-enable them one by one to check which plugin causes this issue.
Regards,
PenciDesign.
