BGPmon regex

I'm trying to edit my prefixes' AS path regex in BGPmon, and when I add a '\s' in the Regular expression field, upon save, the '\' is stripped. Is this expected behavior? The workaround is to insert a '\\s' instead, but one needs to remember to do this on every edit, and I tend to forget which results in panicking the others on our team with false positives. -cjp
