Help! My transitional - 50% whole wheat bread flour & 50% unbleached bread flour - naturally leavened bread is ugly in the score area. Please reference the top photo. Does this appearance suggest what the problem may be? Another batch baked just before this one looked better. Please see the middle photo. This has happened previously - one batch turns out and the other does not - please see bottom photo. I've tried a number of things to figure it out and have not yet. Thanks for any assistance.
