pdir not working with my regex

[SupaMonkey]

Hi Guys,
Examples I'm trying to match (last 5 chars random):
/tmp/.xcloner-10d02
/tmp/.xcloner-a714a
/tmp/.xcloner-f6e8e

My cxs.ignore rule:
pdir:^\/tmp\/\.xcloner-[a-b0-9]+$

Still getting notified. Yes, I've restarted cxs Watch. Please help - thanks

I've also tried:
pdir:^\/tmp\/\.xcloner-(\w){5}$

Even tried the "very broad": ^\/tmp\/.xcloner-.*
Still not working...
