Steps to reproduce
Activate Hivepress featured listings, Activate Translatepress and set another language (e.g. Italian). Set Italian language in the website, go to the search bar and if you search listings, featured ones will be shown twice. If setting again English languge everithing is ok.
EDIT:
I fixed your code XD.
You need to add on line 330/331 (after getting the listing) of the /plugins/hivepress/includes/blocks/class-listing.php this code:
if(in_array($listing->get_id(), (hivepress()->request->get_context( 'featured_ids', [] )))){
continue;
}
