yes, this area is filled with seam sealer. sometimes it shrinks and cracks. I dig it out prep and epoxy prime the area the re seal with 3m fast and firm or similar seam sealer. It must be a heavy bodied product, so it doesn't shrink or sag after application. Cut the tip real narrow on the tube so you can get it well into the groove.
