Row Filter Regex OR

I’m trying to filter the input table for JustKnime-it Challege 35. Below is an excerpt from the file and the row filter configuration. It produces an empty table. My regex abilities are weak, but after some research the regex filter seems correct. Any help is appreciated.

Remove the spaces in your expression. They’re being interpreted as literal space characters.

Thanks very much. I need to find a “Regex for Dummies.”
