Just got a brand new 105 bottom bracket (BB-5500 octalink) and cranks. The main body (right) side's threads look clean. But on the other side's threads there is some yellowish grease (it appears) and 4-5 of the threads have a greyish gunky, almost gritty looking material in them. What is this and is it normal?

The grey stuff is micro-encapsulation. Thread lock applied at the factory. The yellowish grease, well my best guess would be grease. :)
