I have an old Sony STR-AV1010 which support only AV1, and a newer Sony STR-DA5ES which supports both AV1 and AV2 modes. The newer Sony STR-DA5ES Harmony default dataset was AV1 but I needed to use AV2. I added your STR-DE885, and it defaulted to AV2 but you probably use AV1 - go figure. Anyway, do as suggested by Remotevisitor, teach it any missing input commands, then reconfigure the device "Adjust Inputs" accordingly.
