Ahhhh...THERE'S the problem. One of the uMIDI listings was set up by Intellijel...who locked it. The other one (NOT set up by Intellijel) has the actual information.
This is a running MG problem. The only way to fix it (that's doable, really) would be to get into their account and UNlock it. Then it would be possible to change the module's status, but any sensible Internet site like MG doesn't go around hacking into user accounts. Other solutions are apparently much more complex and could screw things up. Ultimately, it comes down to makers paying more attention to what's technically THE modular database online. Hell, Arturia even posts the website's link in their synth manuals!
