When using FeynCalc in Mathematica 9, there are lots warnings when loading the package
 something like this:

NonCommutative::shdw: Symbol NonCommutative appears in multiple contexts {FeynArts`,HighEnergyPhysics`FeynCalc`NonCommutative`}; definitions in context FeynArts` may shadow or be shadowed by other definitions.

Does these warning matter?

And for the input:


the output would always have a prefix Global` and it will appear anytime I use the variable q1

How to solve this?
