As a guess not knowing the radio it may be a question of selecting mode 1 vs mode 2, or the individual channel assignments as suggested above. Did you set up a different model memory for that receiver? It may want the channel assignments or mode one vs mode 2 selection.
I only replied because I have accidentally selected the wrong mode with a computer radio before, I did it programing a new plane.
Or perhaps you got for mode 1 receivers, like I said I know nothing about that radio but the channel selection you described is a mode 1 vs mode 2 issue. Perhaps they were produced for overseas and shipped here by accident or it's something you have to program for this radio setup.
Just something to look into.
