What should I do?

I’m knitting a sweater in double rice style but I think I messed up something (pictured above, a big hole in my sweater) but I still have the same number of knits… So I don’t know what happened, what is it? Is it normal or should I re-knit it?

Thank you in advance!

It’s a little difficult to see what’s going on. If your double rice stitch is continuous and you haven’t changed the stitch number then you could just use some yarn or sewing thread to close the hole from the wrong side. Usually just a single stitch is all that’s needed.
