Is there any way to reset achievements ?
I tried method to get this achievement for x360 but no luck

Try beating two again?

I got 100% in game and I also completed Advanced 3 times.
I don't surely know how does it happen but I think its about saving/loading .

I have that as well I think.
I've done all six maps, but I still haven't got that cupcake achievement. Its shocking.

Guys on x360 don't have sv_cheats 1 command but have same bug.

i don't even have the console enabled and a bunch of achievements have been glitching for me in all 3 games. Sometimes they will finally say complete randomly when im not even doing anything remotely close to that particular achievement.

Maybe it has something to do with internet connectivity?
