Export Motion Graphics template - does nothing...

I've been trying to create a lower third in Premiere to use on other projects but I'm hitting a wall.

I have created a lower third with a .ai logo and a rectangle box around it.  Text appearing from masks and the whole thing looks great (IMHO) with intro and outro times specified so I can stretch the title if needed later.

Problem is when I go to Graphics > Export Motion Graphics template ... nothing happens.

It's as if I didn't click anything at all.

I have the latest version and want to create the lower thirds like this rather than in AE so I can use the intro and outro timing.

Does anyone have any advice?
