I'm in the process of installing a Koger sunshade in our 9A slider. When I slide the fabric on the bows, if I slide it to the first angle in the bow as in the photo, there's still some lateral slack in the fabric (or some extra width beyond the bow). Is this how it's meant to go, or is the intention for me to slide the fabric somewhat over that angle toward the channel, before adding the drop of superglue?
