TV-show Scanner find nothing

Hi,
I’m using LibreELEC version: 8.0.0 under RSPI-3. build: 17.0
I am trying to scan a directory with sub directories, that every sub-directory content a series’s season.
The names of the sub-directories is as in the picture.
The scanner finds only the Legion series (the real name is without .david), and if I change the other directories to “clean” names it finds all the series.
I dug a little bit in google and I found this.
I’m using in Regex as in the picture (you can see that it finds all the names in group zero), but for some reason the scanner still finds nothing.

How & where I need to put the Regex?
