Regex not working for importing books

[kokkie20]

Basic Information;
Calibre Version: 5.5
Windows 10

Issue;
I want to use the regex option in calibre when importing books.
I made up a regex (Well with help from the internet!) and want to apply it when importing ebooks.
But the regex option is just not working/ignoring the regex i apply.
It is tested online on a regex tester/debugger and there it works perfect for what it needs to do!
See here: https://regex101.com/r/dWo044/1
Let me explain some more...

I got files called as example:

#_MIST_#_... Cartoons - 02 - Dieven Cartoons.cbr
#_MIST_#_1850 - 02 - Donald.cbr

What i want the regex to do is copy the text between "#_MIST_#_" and between the first " - "
That i do with this:
(?<=^#_MIST_#_)(?P<series>[^-]+)(?=\s-)

So: #_MIST_#_... Cartoons - 02 - Dieven Cartoons.cbr
The title becomes: ... Cartoons
And for: #_MIST_#_1850 - 02 - Donald.cbr
The Title becomes: 1850

But when i click test (When i enter a file name in the regex tester in calibre included is the extension!)
It just don't add the text part to the correct textbox (In series).
Am i doing something wrong or?

Thank you in advance

I uploaded image to show what i try to do:


As seen on the image you see the regexp i added into the software
The regexp i gotten from "The Fourth bird" is used here.
"Bestandsnaam" is translated: filename
"Titel" is translated: title
"Reeks" is translated: serie

But as soon as i test the code it just shows the information like the image.
But what i want to show is like this. Note image is photoshopped:


On the regex tester it works perfect, but sadly on calibre it aint working.
Does anyone got a idea why and what i am doing wrong?

The problem is the underscores. The last line of the comment before the regex says, in English:

Note that underscores in filenames are auto-replaced by spaces.

And for what you are trying to do, the following appears to work:

^# MIST # (?P<series>[^-]+)
