Well, you're not the only with that problem. but here, it has some "random" icons at first. Then, if you scroll down, it's alphabetically ordered. I can't change icons that are in the end (Web, Phone, E-mail, etc) to the Top lines. But i can change those between them (let's say, changing to the left).
The first icons, (until "Shop" appears) can't be moved.

I would really appreciate an answer on how to fix or if it will be fixed.
