Old Posi giving incorrect challenge badges.

[Backseatsman]

I was playing on my level 50 +3 Necro/Dark Mastermind on the Everlasting shard, doing flashback missions through Ouroboros. I did a solo run of "The New Recruits" (old Positron TF) with the No Enhancements/No Travel powers challenge settings. The New Recruits is a level 15 TF so I expected to receive the "Refrained" and "Lessened" badges for doing this, but upon completion I was instead rewarded with "Undertaker" and "Unenhanced" (the level 46-50 equivalents of the same challenge badges). Has anyone experienced something similar?
