I've recently brought a Little Phatty second hand, hadnt had much time to play with it but seems might have a few problems

Its a recent black edition, only about 4 months old. Anyway, a few of the issues I've spotted:
1) When messing about with presets, the preset light goes red (or is already red actually!), and when you press the preset button to go back to the original it just stays red and reads panal active, it breifly flashes orange as do the lights on the various pots, but it stays on the modded preset.
2) When moving a pot around if you go to an inbetween kind of setting I believe you should get two of the orange lights around the outside of it light at the same time, whereas on mine the two lights kind of flicker in a strange way...?
3) When flicking through presets and landing on one, sometimes the lights outside the pots take a while to settle and creep around the outside slowly until settling, strange?
Anyway, it doesnt seem right. It sounds ok I think, and its practically in brand new condition, not a mark on it so I cant believe it would be faulty already...? Is it worth doing a firmware re-install or something along those lines? I've done a factory reset and master reboot, didnt seem to do anything to help. Or maybe this is all perfectly normal and im being wierd! Boot is v1.1 and Rev: 3.1S, 671.
Any help greatly appriciated!
