Ahhh pattern help

So I have this pattern for a bikini. I can’t seem to figure it out the math does not make sense to me. I wrote out each row so i could make sure I was not missing anything is goes as follows:
Cups for bikini:
cAST ON 37
rs dec: K 16, k2tog, k1,k2tog, k 16
ws: P15, p2tog, p1, p2tog,p15
rs dec: K 14, k2tog, k1,k2tog, k 14
ws: P13, p2tog, p1, p2tog,p13
rs dec: K 12, k2tog, k1,k2tog, k 12
ws: P11, p2tog, p1, p2tog,p11
rs dec: K 10, k2tog, k1,k2tog, k 10
ws: P9, p2tog, p1, p2tog,p9
rs dec: K 8, k2tog, k1,k2tog, k 8
ws: P7, p2tog, p1, p2tog,p7
rs dec: K 6, k2tog, k1,k2tog, k 6
ws: P5, p2tog, p1, p2tog,p5
rs dec: K 4, k2tog, k1,k2tog, k 4
ws: P3, p2tog, p1, p2tog,p3
rs dec: K 2, k2tog, k1,k2tog, k 2
ws: P1, p2tog, p1, p2tog,p1
k3tog

The intarsia goes as follows:
on row 17 k 14sts work 9 chart sts, k 14 (And there are 8 rows in the intarsia part)
This does not make sense there are only 17 rows! and each row decreases by two yet the k 14sts work 9 chart sts, k 14 adds up to the original cast on # of 37. I dont even want to do the intarsia for this part (although I will do it on the bottoms) I did a sample one and just following the 1st section (no intarsia) it comes out too small, I must be missing something!
