That's correct, I'm glad we worked that out :)

Everything seems to work now, thanks again!  I hope you don't abandon anything, you have done a great job and I'm sure everyone is very appreciative of all your hard work.  I know I am!

Does not seem to have worked

Ok that worked, BUT as it always happens something else seems to have broken now as my top bar looks like this:

The filter seems to be working great so that should fix my problems, BUT now it looks like it's pulling some kind of genre info in that Publisher icon section, maybe related to the reason why you previously ignored non-alphanumeric :D

Ok that makes sense, and yes I think allowing non-alphanumeric characters in my case dashes (-) for the imprint folder naming, (!) marks for those publishers that have that in their names like Boom!, would take care of my issue other than having to set the publisher names to be Publisher=Publisher - Imprint

Thanks for the feedback!

So for example, I use Comic Vine Scraper on ComicRack which tags them as Publisher "Boom!" and Imprint "Archaia"

I then save them into a folder Publishers\Boom! - Archaia\Mouse Guard - The Black Axe\ to match the folders from the Comixology-Ubooquity-2020.01.19 pull that was hosted online.

Do I need to be manually changing the metadata for the Imprints to be "Boom! - Archaia" in only the "Publisher" field?

Also, is the ! mark getting removed somewhere too which is why it isn't finding "Boom!" as a publisher?

I am having an issue with the Credits section of the individual comic issue pop-up when it comes to imprints, it seems.  For example below when I am looking at the series page, the proper Imprint publisher icon and name show up on the right side.

However, when I click the individual issue, the Publisher icon on the top right is of the parent publisher, but not the Imprint publisher.

And in other cases for example below, it is only trying to pull the first word of the imprint publisher name and thus not finding an image?
