I have lots of songs loaded in the current playlist (the list on the right hand side)

I wanted to queue a particular track, so I used the filter text box above the list, right clicked the 4th track, and clicked "Queue track" but the track wasn't queued.

when i removed the filter it showed that the 4th track of the entire list was queued, not the 4th track of the filtered list, and when it went to the next track this was confirmed.

It should have queued the track I had right clicked instead.
