How to use regex in bubble Part 2 

This is exactly what I was looking for, thank you

I need to remove list numbering, ie: "1. " and "2. " from some dynamic content in bubble, the numbers may or not be there but when they are there, they appear at the beginning of a paragraph, my pattern is: (?:[[1-9]\. |)(.+) but when applied to bubble's regex filter it does not seem to do anything, does bubble not support non-capturing groups, or am I doing something wrong?
