Icons not showing correctly in inventory menu

[KanlyRC]

Hey guys
I've got a fresh install of Minecraft with Forge loaded for 1.7.10 I loaded Buildcraft version below and when create a new world the icons for items are all garbled up. I only have Buildcraft loaded with no other mods. Any thoughts as what could be causing this?

computer: MAC

files loaded:
forge-1.7.10-10.13.4.1558-1.7.10-installer.jar
build craft-7.1.16.jar

I've attached a screen shot of the problem i'm having as well.

Thanks
Kanly

This isn't an issue on our end, unless you can prove that it works as intended if Buildcraft is installed any other way.
