Golden Gift achievement glitch

[xbetax275]

I was wondering if this happened to anyone else. I went to teh interet zone and did the kid xmas level pack. I looked at each level, and tried the 4th one a bit. Then, I went and just did a "I'm to young to die" level pack. It gave me a pack of 20 and I started on the first one. After I completed the first level, I got the achievement for playing one level of the kid xmas. After 5 levels of the "I'm to young to die" pack, I got the golden gift achivement. Does anybody know why?
