chess.com analysis a random move generator?

I analyzed the same position, to the same depth, on the analysis board and by clicking analyze on a game I played. Not only is the scoring of the position different but there is only one overlap in the top three moves between the two analyzes. The top move in both don't make top three in the other. What gives? Am I reading it wrong?

My engine shows d5, Be7, and a6.

The "slight" difference is that Black has played 2...d6 and not 2...e6.

Please notice this the next time you will waste electric energy for nothing- either now, or under your next troll account.

Why play d6 and d5 then?

How did you ever become an IM and not learn about transposition and different move orders? 

Except not a free user...I'm a fancy platinum member. I don't know however if that is higher or lower than diamond. But I'm certain it's enough that chess.com should let the engine run for me.

Then click the gear next to the depth where it is reading 20 and change it.
