Confusion with pattern

I’m knitting the Square Beck Camisole by Hanna Bebe on Ravelry.

Ok I am currently on this step doing increases under the armhole, where you do one increase each side on the RS and the the WS you ‘knit rib as established’ I know I’ve done something wrong here bc this awkward triangle should be part of the ribbing somehow, but I don’t know how to incorporate it because I’m not increasing by 3 each time.

I’m not going to frog, but my goal is to finish the front piece correctly and then do the back piece correctly as well

If anyone could please help me!! I’m literally begging haha
