Wizmote remote Presets & Playlists - Strange Behaviour

I have a Preset at location 1, Playlists at 2, 3 & 4.

Upon power up pressing button 1 recalls Preset 1 as expected.
Buttons 2-4 recall the playlists as expected.
But pressing button 1 again recalls Preset 1 but only for as long as the next item in the previous playlist takes to come round, ie the playlist is still running.

If I use the web browser to select the Preset it works as expected, ie the Playlist is cancelled.

Any ideas?

Is there a JSON command I can add to P1 to cancel any playlists?

Ta.

A known bug. Already addressed.
Will be fixed in next release.

Cool, thanks
