Hi @abzlevelup,
the bug is visible at https://acli.tastinglab.it/categoria/servizi/cultura-e-turismo/
Now to do a rough bug patch I have translated the term category in the italian language to category (and not to italian categoria), this seems to work but I noticed many other bugs when I upgrade event calendar to the last version. I’m not sure if they are related to the same problem as an example if I go to next events the URL became something like this https://acli.tastinglab.it/eventi/category/(/?:%5B^/%5D and is not working
