Events Filter not working

[GMTeams]

Contao 4.13.36
PHP 8.2.17
tags 4.9.14

I have a working setup for a news module:

• frontend module "Tagcloud (News)"
• frontend module "News list"

However the "same" setup is not working for events:

• frontend module "Tagcloud (Events)"
• frontend module "Events list"

For testing purpose the configuration of the modules is mostly on default parameters.
For each setup I have an archive with 2 test entries, and each entry has one tag.
As said before, the filter works on news, but not on events.

I tried several configuration settings. Does anyone else have this issue?
Thanks.
