Missing all the upgrade buttons after downloading this plugin

Hello just bought this plugin and I am messing around with the fetures to teach people how to use it but i have no buttons for wallpaper, metal, stone, HQM.  The only icon i have is the wood option.

Any help available to explain this a bit?  Thanks!
