Hi, Stan. I appreciate your troubleshooting efforts and detailed report, here, but we do not provide theme-specific support, per our Scope of Support / Terms.
However, I checked out your site’s Events page (thanks for including that URL) and I believe this CSS snippet should solve the issue:
body.post-type-archive-tribe_events #tribe_events_filters_wrapper label span {
display: inline;
}
This will override the CSS rule from /wp-content/plugins/the-events-calendar-filterbar/src/resources/css/filter-view.min.css that sets the display to inline-block. There must be something about this that conflicts with your theme’s CSS.
Please let me know how this works for you.
