FUZZY_XPILL FP hitting all Travelodge emails

[Sebastian Arcus]

I have a client which handles a lot of hotel bookings as part of their 
work - and all hotel booking confirmations coming from Travelodge (a UK 
hotel chain) hit FUZZY_XPILL.

I've tried looking at the regex of the rule, but can't quite get my head 
around what it is supposed to do, and can't figure out why it triggers 
on all the Travelodge emails either. Could anybody provide some hints - 
or have others seen this as well? I can provide some sample mail, if it 
helps. Thank you.
