Initial state: Three Input Streams (Input-S1, Input-S2 & Input-S3) with each having 64 channels. Three Output Streams (Output-S1, Output-S2, Output-S3) with each having 64 channels. Channel ordering (sidenote): When navigating to the "Stream Associations" page, the order of the streams in the drop-down started with the 64 Input-S2 channels, then followed by the 64 Input-S3 channels, and then at the end, the 64 Input-S1 channels. It would be great if these were sorted alphabetically or optionally when added. Behavior/Issue To simplify the association processes, I deleted Input-S2, Input-S3, Output-S2, Output-S3. However, the channels from these four streams remained in the "Stream Associations" drop-down list even though they should have been deleted along with the Streams which doesn't appear to be the case.
