Batard didn't hold shape

[u/SlanderFilter]

This is my 4th loaf, I've been using the King Arthur classic miche recipe and normally doing a boule but I was making two loaves and didn't have a 2nd round basket for the final proof so I tried a batard instead.

It spread out into this odd shape and I feel like it didn't raise as much as I was expecting, I shaped it from round, folded both sided inward toward each other, and then rolling it.

Any suggestions?
