Hello Diane and welcome to the Cow Audio Forum.
Eric has given you good advice.
About your surround anomaly. Without being there to see and hear where things were routed for your surround project, it’s difficult to give a plausible conclusion.
Was your system configured correctly?
Were your speakers and amps adjusted correctly?
Was the playback system configured correctly?
etc.
An error in any of them, all of them or something else could be responsible.
