The damage is a clear indication that the "shear webs" were installed incorrectly during wing assembly at the factory. The shear webs were installed with the grain running horizonal with the wing spar instead of vertical. Your damaged wing is fixable and is fairly easy to do, it just takes a bit of patience and time. If you purchase a new wing set, the new wing set may have the shear webs installed incorrectly too. You will be able to confirm if the shear webs are installed correctly in the new wing set by inspecting the shear webs that are visible in the land gear mounting area.
See attached link for the kit build wing manual, page 15, step 15, on shear webs installation.
