Sorry if this has been discussed before...

I checked-in for today's flight online yesterday and printed out a boarding pass which contained all the goodies -- Sky Priority & TSA PreCheck (I have GE). When I arrived at the airport and checked my bag, the Sky Priority agent reprinted my boarding pass and on the new one I lost the TSA PreCheck.

I realize PreCheck isn't guaranteed but is this a common occurrence (to lose it on a reprint)?

Not a huge deal as I still had access the SP lane -- took ~10 minutes to get through rather than ~3 minutes in PreCheck -- but it was irritating hearing people in the PreCheck lane (which was in close proximity) confused on why they need to keep their shoes on. ;-)
