R# 4.5: Code completion not so complete?

Look at the following screenshots:



I've been thinking about this all day, and i don't believe it's a bug, there must be some rational explanation for it: In the first screenshot "Point" is not in the code completion list, yet in the second screenshot it is....why? Is there a setting i must change? Is there something special about the Point struct? I have seen this behaviour only for the Point struct and it's pretty consistent.

I'm searching through the Issue tracker at the moment, just in case it is a bug, but it's going very slowly and no luck so far...
