The sweet taste is because of the adjunct to malt ration. It's 50/50 in their standard recipes but they are good to get you started on the process and understand the ingredients.
Two quick changes will give you beer that is orders of magnitude better:
1) Replace the Booster with one of their UMEs (or pick up some LME/DME from your LHBS)
2) Pitch 2-3 times the yeast they provide you with. 2 grams in insufficient. The yeast itself is good quality, just poor quantity.
Of course you can always pick up different yeast from your LHBS, too. But those simple changes will produce much better beer quickly.
If you like what you've done so far, you're in for a real treat when you use more malt.
Cheers.
