I would say that your base bevel is probably too high. My experience with sports authority is they tend to over-bevel the base angles. Last year, I took up racing and brought my skis in for a tune. When I got them back, I measured the base angles on them and found they were 2 degrees!!!! I ended up taking them to Joe's ski shop and getting those set to 0.5 degrees.
Some people said they might not be de-tuned at the tails and tip. I'd argue the opposite. If the tails and tips weren't de-tuned, you would have a problem with the ski being too "hooky", not squirrely.
It's possible there's just too much wax on it that didn't get scraped off, which would cause the edges to be off the snow a bit and make them feel squirrely. You can check this easily by looking at the bases to see if the transition where the base meets the edge is smooth. If this is the case, then you can just get them scraped better, brush the excess wax off, or keep skiing with it until the excess wax gets skiied off.
