Were these TWO products added after the migration?
I have no experience with migrating from OSC to ZC and can't tell you the difference. HOWEVER, a script called Zen Magic by MagicOne is used for storing and updating products into Zen Cart in a similar manner as OSC and I know that these products are NOT extractable by any of my mods. What you may want to try doing is exporting all of your products out of your database and then use excel to put them into Easy Populate file specifications and update your site using Easy Populate. The products should then become extractable from the database by these mods.
Perhaps DrByte, Ajeh or one of the other developers with first hand experience with OSC could tell us the difference in how products are stored in the database.
