Bill,
There are few things you can do but this is what I do.
1) brush more wax on those supers.
As a new hive you probably don't have access to melted wax so try this:
Take the super off the hive and move one or two of the undrawn super foundations into the deep brood box. Choose/remove two deep frames that are are already or mostly capped with honey out. Move the new undrawn super frames near the middle but don't separate the brood with the two consecutive undrawn frames ( stagger them in or bookend them). I know they are a lot shorter -no worries. Leave these frames in there for a few days - check them to see if the bees are start to draw comb. Once you see them drawing comb but before the queen lays eggs, remove the superframe out and replace the deep frames. Now you will put the super back on, reposition the two super frames that they started in the middle of the super. You could keep excluder off but it is important to check to make sure the queen isn't laying up there. May be easier to excluder back on.
The hope is that the two super frames will bait more bees to come up and draw foundation.
Give it try - but you need to stay on top of the supers in the brood box as the bees will quickly start to draw comb under those shorts. If they do - you will need to cut it off.
Give this technique a try and let us know if it helped.
