Field extraction regex problem

I have logs that looks like thos

1: username

So I would like to extract the username from two systems named system1 and system2, when trying to do this in Splunk it fails using a regex that works when I try it outside Splunk

(?i)(system1|system2)(?-i) (?<SYS_Username>[A-z]+).* 

If i do

(?i)system1(?-i) (?<SYS_Username>[A-z]+).* 

It works perfect, but only for one system.. The problem seems to come when i introduce the ( | ) syntax.

Hi,
Could you try that :

(?i)(?:system1|system2)(?-i) (?<SYS_Username>[A-z]+).*

(?:) says "don't capture"
