smaller one work fine, larger one isn't straight and goes up questionable.

I'm sorry that you are having problems with your cordless shades.
The cordless cellular shades are designed to be self-correcting. To reset your cordless shades: Lower the shade down to its full height. Firmly hold the bottomrail with both hands and pull it towards you (away from the back of the window at an angle). Quickly and firmly pull down (popping) on the bottomrail 3 or 4 times. Raise and lower the shade, repeat as necessary.
These steps should rest the cordless motors in the headrail so that the shade will raise and lower properly. If these steps do not work, please let us know and we will remake or repair the shades as needed.
Thank you for trying these trouble-shooting techniques. I have ordered you a new shade to replace the one that is defective. I appreciate your understanding and patience.
