Shortening patterns on OP-Z

Hey, I’m wondering if anyone can help me with this and if it’s possible?

I copied a pattern and edited it a bit for a new section (muted a bunch of instruments for a breakdown section). My problem is that I want to shorten this pattern to half the amount of bars. I have tried to shorten step count and length on each track but when I chain it with the other patterns it still stays the same length overall!! Anyone know how to shorten a pattern when adding it in a chain? Any help appreciated, thank you!
