People keep dropping out of Prop Shredder (bnb)

Why is this? I think it might be spacing, but when i hold forward during j.h, qcf.m, j.h Dante doesn’t seem to move at all. Sometimes they pop up from the Prop Shredder and other times they don’t.

sometimes they pop out if you get them on the very (very) tip of the sword, unless you are going for double acid rain combos there’s no need to aim for the tip.
most of the times if they pop out is because it’s too late into the combo.

Thanks! So does that mean I should stall for a few frames before i press S after S > H? So do S > H > pause > S

yes. a slight pause is enough.
