N00b: Can't understand the analysis

Hi guys! New to this forum and a bit new to chess so please be patient

Have been playing a lot of games and tried to use the analyse function to improve my game. Sometimes it feels like "blunders" are wrong call from the computer but since I'm new I suspect myself.

Example in the attached screen-shot. Why does the computer want me to move my (white) queen to D8 and be threatened by the black bishop in F6.

Thanks / E

The analysis shows the suggested line. The idea is that after black takes the queen white get the material back after pinning the black queen to the king.

The reason it is marked as a blunder is that the suggested move had a better evaluation. But both moves are completely winning, so it isn't a true blunder.
