It's confusing at first, but as the Properties panel is "context aware" the contents change anytime Premiere thinks you've selected one very specific thing.
So you can select the graphic/mogrt on the sequence, and only see the size and postion options in the Properties panel ... because as far as Premiere is concerned, you have only selected the 'entire' clip.
Now, click on the Program monitor in a text or shape section ... and suddenly, you see all the old EGP controls appears, as now, you have "selected" the right thing. It's odd that way.
Everyone's mileage always varies ...
