To be honest I don't completely remember the context anymore after all this time. I think my intent back then was to create a controlled DSM and RMIR was misbehaving for some reason, but as previous comments stated this is a real-time DSM (unsure what is the actual difference in practice between them in this particular remote); I am not sure if the use of real-time here was my mistake or a genuine bug in RMIR. Anyhow, the fact that RMIR can open the file now and warn about it indicates to me that...
Protocol parameters overwritten by RMIR
Also: if I upload such configuration to the remote, then I can no longer download the remote.
"Error loading file" when it contains DSMs bound to shifted keys
Bug fix: Do not discard comments when importing Girr files
