Hello. Thank you for contacting the Toolset support.
Can you please share admin access details and let me check whats going wrong with your setup.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
I found that you added the two frontend filter to filter with the same URL param "wpv-wunsch-hilfen-alltag".

I changed the another filter URL param to "wpv-wunsch-hilfen-alltag1" and I can see its working and I can see the "testhilfe" when I select the "Haushalt" term.
Can you please confirm it works at your end as well: versteckter Link
