Query: Missing episodes?

I love Frasier, and am really glad that it's available for free streaming on Amazon Prime. However, I find the streaming experience has a lot of room for improvement. Not only is it not as seamless as Netflix, it also leaves out certain episodes! The seasons since S6 are not complete -- only 1/2 or 2/3 of the episodes are available. What gives?
