Comparison Criteria exclusion doesn't work

Hi,

I'm trying to exclude line with date of my comparison criteria but for now it doesn't seems to works.

my configs looks like :

#

# Tue Sep 08 00:20:45 2015 CEST

# box type             : VSP-8284XSQ

# software version     : 4.2.1.0

# cli mode             : ACLI

And I want to exclude the 2nd line

I've tried this regex : ^# (Mon|Tue|Wed|Thu|Fri|Sat|Sun)

I also tried : ^(# )(Mon|Tue|Wed|Thu|Fri|Sat|Sun)

what did I miss ?
