Sure! I believe this issue is related to one of the recent WPML versions, but I'm not sure yet what exactly it is. Basically the result link is missing one parameter, so the redirection is not fully correct.
The fix for now is really easy, but it needs a small custom code snippet. Add this custom code to the functions.php in your theme/child theme directory (copy from line 3 only!). Before editing, please make sure to have a full site back-up just in case!
If you need help with this, just add temporary FTP access to the ticket, and I will do it for you.Best,
