Q: only 147 photos are being shown on my photo stream with the new photos version

I've taken around 600 new photos the last two weeks. But on my photo stream album are only 147 photos being shown.

How can I fix this problem? I've tried to turn and off photo stream. But nothing changed.

I use photos Version 1.0 (209.52.0) on a mac os 10.10.3

Thanks
