Collect Images: Wildcard not working with filter attribute "tag"?

I’m a little confused about the use of the wildcard.
When I use the filter attribute “tag”, the wildcard only works at the end of the string.
When I use it at the beginning or in between nothing will be found.

With other filter attributes the wildcard I can use at the beginning or in between. Should’nt it work like that also with the filter attribute “tag”?

I’m using dt 3.4.0 with manjaro

Same problem using darktable 3.4 / windows 10!
I could not solve it either.
Decided to rename the path of my tags …
