Hello.
Please note that in OSM all tags are always in lower case. Upper case tags are invalid and ignored by all software.

Based on the text of your Note= tag, it sounds like it's more appropriate for the description= tag instead.

Looking at all the available satellite imagery, I'm not seeing anything that looks like a slipway as documented at https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dslipway
It sounds like it should be https://wiki.openstreetmap.org/wiki/Tag:canoe%3Dput_in
Also, slipway=canoe doesn't seem to be a tag used by anybody else.
