Since you mentioned that your items are different to I'm just going to come in here and explain that the reason for that. Although you may both be using item packs with the same or similar items some people's item packs have a different coding order in their items.cfg file than yours, therefore everyone will see the items in different orders. If you guys really want to see your items in the right order you either have to download and use the same item pack or organize both your items.cfg files codings to try and match each other. Best bet is to just download the same item pack though. Goodluck I hope you get your problem fixed.
