Oh wait that’s what I did, upside down in the banneton so I score the non-seam side.
Your crust could be forming too quickly, essentially sealing the score and causing pressure to burst out of other places. You could try more steam to keep the crust softer and allow the score to continue to open up as the bread cooks?
