category archive for specific year shows all years

I have multiple archives with specific categories in sidebars setup with a specific sidebar function.

The archive which shows the category with the id 4 works as it should:
if you klick on a specific year, it shows just the post(s) within that year.

But somehow any other category is not displayed correctly (they show all entries from all years).

when I take a look at the link they are apparently the same:
https://goetz-naleppa.de/wp/?m=2020&cat=4
https://goetz-naleppa.de/wp/?m=2020&cat=8

The page is translated in english if you need to have a look at it.

the archive which works is the news page, the ones who do not work are the other archives for example the radio plays.
