I've seen this problem before, but only with the diabled versions of the buttons, unless the ones that appear green are the disabled versions, in which case you just have to put ReplaceableTextures\CommandButtonsDisabled\ infront of model's path, that will fix the problem most likely.
Hey ThaAthael, that was uncalled for, he’s new to the Hive and wasn't aware it was an often asked question, so try and be nice alright?
@wickedcool: Did my suggestion fix your problem? If not you could go on the Hives IRC Chat and see if anyone can help you there, the link to the chat is at the top right of the home page right next to news.
🔨 Hive's 3D Viewer has been updated! 🔨 It now supports MDX1100 which should fix a lot of issues when viewing HD models in our 3D Viewer. We encourage you to check it out for yourself and report any issues you find in the Site Discussion board.
