No experience with that plane but it sounds to me like you either have an LE or TE switched or possibly upside down. Definitely the ribs should be parallel to forward, not at an angle.
They say the ribs probably wont match the plans but they should be pretty close.
Looking at the pdf file they show the notch end on the LE at the wing tip but the notch end on the TE at the wing root. Possibly you have em both at the tip or the root? That would mis-align em for sure! I would re-check that.
First time builder, it is VERY easy to do something like that. Been there, done that, where is the CA Debonder?

Anyway, thats my 2 cents worth.
