That side screen looks exactly like the trad. Water fills the trough/gully where the plex glass slots in. Without that drain hole the water then fills the trough/gully & runs down the inner side & wets the sills & carpet. Back in 2011 the factory did not bother to drill the drain holes so I drilled mine & have had no water from that area since. The factory did start drilling the holes but not sure when.
