Using 2 of the same MIDI devices with cubase sync

I’ve got 2 behringer td-3’s that i’m trying to record with and Cubase keeps un-checking the box to turn on sync in the project sync gui. So one of them works, but the other does not. All of the other devices I use the devices show up as td-3(1) and td-3(2), but in cubase it’s 2 seperate “td-3” with no identifier. Can Cubase not resolve 2 of the same driver or something?
