Wood blocks between CB housing and cockpit floor (or not)

Greetings all,
It's both amazing and depressing that I can go work on my boat for 3-4 hours and come home with a dozen or so new challenges and issues to share with and query about to you all.
I think this is #3 or #4 tonight...
While dealing with (I think it was) trying to get one last piece of waterlogged flotation out that was jammed partway under the cockpit floor, I took advantage of the hole in my cuddy floor (different post/different day) to shove my iPhone down and snap off some pictures (better than a polaroid camera - That tells you how old I am). Anyway, I popped off a few panoramic pictures, found the errant styrofoam, but also found a piece of wood sitting where I wouldn't expect one to be. I extracted it, and it turned out to be maybe 1 x 1 x 12" piece of plywood or the functional equivalent of it. I stuck my iPhone back down and snapped a full 360 degrees of pictures and found this shot relevant.

This picture is the front of the centerboard housing where it attaches to the cockpit floor. There is a horizontal flange (this is all fiberglass) in the center upper third of the picture. On the right, (on top of the flange) you'll see the end of a piece of 1 x 1 plywood. On the left you'll see that one is missing (that's the one in my hand). Turns out the one on the right in the photo (port side) is loose enough I could pull it out very easily as well.
Should this strike terror in the heart of a DSII sailor? Should I cut some new fresh pieces and glue them back in that slot?
Any thoughts or opinions are welcome... Thanks,
