Unplayed playlist issues

I just upgraded my iTunes, and 14 old songs now have their played count reset to 0.

Today, 9 old songs have plays=0. I wonder how many other songs have their play count changed.

Crossfade was alreayd unchecked with my preferences.

Actually, that was 8 songs and one movie this time.

That is checked. I just played all of the songs that were at zero and they updated to 1. But they should have a much higher than 1. I wonder how many other songs' play count was changed (to something other than 0).

It took this long for another well-played song to zero plays.

And it took this long to happen again. This morning I had one unread podcast, which I postponed listening to. A couple of hours later two well-played songs and two movies were added as unplayed, without my rebooting.

This morning 7 things showed up as never been played. 5 of them are movies. One is a song with the cloud icon, and one is a song without the cloud icon.

Just now three ovies and two songs showed up as unplayed.

An other thing - before this all happened, when I opened that playlist and pressed my remote, it would play all of the elements in order. Now the only way to play something in that playlist is to select one (with my mouse), wait for it to end, then select the next and the next and the next by hand.

Just now, my playlist was open with nothing - and then 3 well played songs and two movies showed up in that list.

The list also has an issue that is new. I select a song, play it, and it doesn't go to the next song anymore when it is done.

Today I have two well-played songs added to my unplayed list.
