Atmos ADM export missing/switching channels - can someone try this?

I am having an issue with missing channels. I created a pan test with me saying “Front Left” etc and they go to the right positions within my speaker setup. If I export the ADM and then reimport the file into the same project, the rear left and rear move to the side left and side right.

I think it’s my setup but can anyone duplicate this issue?

(Using latest Cubase)

can you be specific

12.0.40
12.0.50
12.0.51
?

I was, I said the latest version - which is 12.0.51

just trying to be helpful.

good luck resolving your issue
