Everyday 2 slider not working + making it longer?

Hi,

I have this:

https://www.daz3d.com/morphs-for-everyday-2

+ the basic (yes finally pants to pulled down hehe :D , I wish I could "steal" the sliders and use them on ALL clothes... is that possible *thinking*?)

But, the slider "enlarge all" does not work for one item :( and I wanna move it uover the butt, because... thats how I wear it in real Life too :D

I made a video. (click to play)

Second problem, the short is a 3/4 Short (in german we call it "Hochwasser Hose",=~ High tide pants) kinda... ugly :P I wanna make them down to the feet, is that possible? I did try it with the scale, but then it goes more up. okay... it goes down! (nice!) but...

how to fix this? :) without making it in total too big?

Oh AND, is the outfit also aviable for man? I mean... its fitting pretty good already but... just asking :D

Edit: for the first problem, I found the solution with the "hidden" slider Z-scale :)...
