Need help with this slipper pattern

Following <img src="/uploads/default/original/2X/c/ced9c760d49de5c0f7f5a7ef61eff717e4736ede.jpg" width=“675” .

Im knitting my first set of slippers. Im using phetnex crafting yarn and following the instructions on the back.
I’m confused, what do I do in the 4th, 6th, 8th and so on rows? Does this look right so far? Ended at knit 2 rows. I think if I start with the shaping of the toe, I’m knitting at the wrong end? What did I miss? I followed exactly.

It says “2nd and all alternate rows Sl 1 and knit to end” that’s what you do on even rows.
