Unusual transposition problem?

This is an xml from sib for a horn sextet. The score was transposed but the pitch wasn’t transposed so (in note performer) I lowered the playback pitch by a 5th and that worked, but not in the parts which are transposing the already transposed score. Any advice on how to fix this? Thanks

I assume you tried reloading the instruments via Setup—Change Instrument? I often have to do this for XML imports.

Finally figured it out. Not sure how that went wrong but it’s fixed.
