Hi everyone- this is my first post I believe and it's going to be a whinge, sorry

I am not at all new to knitting, but usually knit homey items rather than clothes, so this is my first cardigan.
I'm knitting the Agatha cardigan by Andi Satterlund
http://www.ravelry.com/patterns/library/agatha-6It's hard!!!!!
The pattern provides you with 3 panels separate to the instructions. It is a multi-size pattern.
The medium size says cast on 69 stitches (but so does the small!!!) fine, ok, cast on.
First off, when it instructs 'work panel 1' am I to just knit row 1 from panel 1 and then continue?
That's what I've been doing, and it seems to work ok but now I'm stuck: the last two rows (10 and 11) are repeated 17 times. Row 10 ends with 71 stitches, row 11 ends with 77 (which coincidentally is the final stitch count of the large)
The final stitch count should be 69.

Am I completely missing something?
Here's a screen shot of rows 10 and 11:

I've nearly killed my fiance over this pattern but I so want to do it, any help will be much appreciated
