Delta Shinx

I just caught Delta Shinx and saw that it had poison point. I bought an ability capsule from the man in the house nearby but when I used it on the Shinx the ability changed to Sniper, and not Vampiric as I had seen on the wiki. Is this a bug, or is the wiki not up to date on that?

Ensure that you’re updated to 1.2.5, as Vampiric was only added as a secondary ability in the most recent update.
