Its not wrong if you see this in the "recent activity" area - the zero you see is in the column for and refers to RDM, which is correct since those show up in a separate posting. The amount of PQMs specifically for card purchases only show once they appear in your statement, and not in recent activity. At least that's the way its been for me since March '12.

You will see the PQM added to your total, and will also show the amount added in the recent activity summary for PQM under the non-airline activity section. Since this is practically the only way to earn PQMs for non-airline activity, the total should almost always match your UA card spend credited (up to 5000/year, of course).
