It looks like there are two English audio streams, which causes two variants for each resolution. We should be de-duping resolution selection to ensure we don't show duplicates if there are multiple "resolutions" of audio.

In this case, the reason there are two streams is because there is a 2-channel and a 6-channel audio option. ABR is only given the tracks that match the current channel count, but getVariantTracks returns all of them. We should also be filtering out tracks based on the "current" channel count.
