First, no it's not normal, you should see the other plane on the taxi way.
Yesterday before my flight I installed IVAP again, and the brand new MTL v2, when I connected IVAO (click conn, and that's it) and a 737 from TAP popped up just on my left, even had to move my plane slightly not to touch its wing with mine.
Second, local traffic things ? If you mean AI traffic, before flying online be sure to put the AI traffic to none. If you didn't mean that, I didn't get your question right, sorry
