Help! Strange behavior of the new APP

Since the last 2 days I have a strange problem with the new APP.

1) In UPnP  I select an album, I press the three dots at the top right of the page and select PLAY NOW, it always start from track n.2 always jumping track 1. If I go to see the PLAY QUEUE I find that track n.1 is in the list but strangely in the last position and it plays for last.

This happens only since 2 days, before it was ok.

It happens on all my devices (iPad 3, iPad mini and iPhone 6) all with the new APP.

It does not happen with my iPad 2 where I still have the old app (N-stream) so this means that it is not a problem of TWONKY.

It is not a particular problem with TWONKY because it happens also when I use other server UPnP  with different LIBRARY.

As further information I have experienced that:

A) After selecting an album if I touch the first track then it starts playing all the songs of the album from the first one and also in the PLAY QUEUE the order is correct.

B) If, while some other music is playing already, I touch the 3 dots at the top of the page (as in point 1)  and I choose QUEUE LAST  then the PLAY QUEUE is correct and track n.1 is in first place where it schooled be.

3) If i make a PLAY LIST from the album, the resultant PLAY LIST is correct and plays the tracks in the correct order.

Does anyone have an idea of what's going on?
