It is happening in about 20 measures of the piece, and the rest of the time they end up in two layers as they should. I can’t find the proper “condensing change” to deal with this problem.
Sorry, I didnt mention that automatically the two instruments arent condensed in this passage for whatever reason, and when I apply manual condensing in the way you suggest that is what gets me this smushed-into-one-layer condensing.
