Both hands look like occasions where you have just been a little unlucky. Its not a total surprise to see AK limped at 25nl, enough players think its worth letting more see the flop and hit something while they sit back and slow play tptk which often gets them burnt. Two pair vs a better two pair is unluck as is set over set.
I would just call them unusual plays and carry on (plus i wudnt push the two pair but i think its agaisnt the grain to see AK unraised but it is not to see AA unriased preflop) at 25nl.
Just be aware that it can happen, tag the players and carry on.
