Contacts with wrong missions

I ran into an odd situation today with my Dark/Dark Dominator, Machinator Magicus. I had gotten the 'Save law firm from DE' mission from Lou Pasterelli in Brickstown (save 15 lawyers, with an automatic followup fedex to Wilma Peterson) and run through it without serious issue. What was odd is that I got this exact same mission again a couple of hours later from Jose Escalante in Founder's Falls -- save 15 lawyers (this time more nastily distributed -- it was a small map, and there were two rooms with 5 hostages each in them, which made for some... entertaining... aggro management issues), with a followon fedex to Wilma Peterson.

Ignoring the fact that ParagonWiki's list of missions that Jose Escalante gives doesn't have this one in the list at all, I had understood that it was long a feature of the game that there were two contacts for each level range and origin that gave out the same missions, and the game made sure that you would only get one of each pair, so you wouldn't get the same missions over again from two contacts.

And Jose is ripping off other contacts, too; he just offered me the "Stop Archon Manetti and close the portal" timed mission that I'd received (and completed) from Peter Steinitz. Looks as if I'm going to have to give up on Jose Escalante as a contact unless I want to redo other contacts' missions.
