The thing is it's all well and good converting, but you're dropping old design into a modern and good looking sim, it just doesn't sit in the default scenery well. We've come to expect very high quality from Orbx, and for me the issues I've spotted mean that those two products don't live up to that expectation.
Don't get me wrong, as a alpha/beta tester of MSFS I know I should reserve judgement for the final release products and I'm basing my opinion on pre-releases, but IF these are what is going to market then I'm afraid I'll hold off and wait for better versions.
