Kerdi Drain Sounds Hollow (Pics Included)

I'm using the hybrid Schluter Kerdi Drain + Hydroban method in my shower. I had to glue the Kerdi Drain to the drain pipe prior to pouring the mud shower pan since I have no access from below. Mud shower pan was poured yesterday using Laticrete 3701.

Now that the pan has dried, I fear that I may have a problem. If I tap on the Kerdi drain, it feels solid all the way around except for a small section. The section shown between the screwdrivers has a definite hollow sound to it when I tap on it. I know there is mud underneath, but I also know the mud is not all the way upto the underside of the drain.

There is even a small hole that is visible in the second photo where it is obvious that mud is missing.

Do I need to worry about this?

If so, what can I do?

And, is the whitish discoloration on top of the mud normal?
