Quick hoobuy qc question from a new user

Quick question for the community - I'm trying to use hoobuy's qc feature but running into some issues. I've followed the guides I found but something isn't clicking. Specifically, I'm trying to order hoodies and the process seems different from what others have described. Has anyone else encountered this? The interface looks different from the screenshots I've seen. I've already tried clearing my cache and using a different browser. Same result. Any suggestions would be really appreciated. I've been stuck on this for 26 hours now. Thanks in advance!
