Unwanted nodes display in BaseCamp

I view Lambertus’ OSM generic routable in Garmin’s BaseCamp. Every node of a wood near me displays. I have looked at the nodes in JOSM but cannot see anything amiss: each has been plotted without any properties added. Here are the id and coordinates for one node: 500915665 (51.5119025 -0.9143758).
I should be grateful if someone would investigate this issue for me to provide an answer, hopefully.

It’s an error on osm:
Underneath the forest polygon (http://www.openstreetmap.org/browse/way/41085570)
is another incomplete polygon drawn which should be removed: http://www.openstreetmap.org/browse/way/41085568

Many thanks!
I have deleted the incomplete polygon. Out of interest, though, how did you detect it? I tried using Ctrl but without success.

I saw that the node that you mentioned, http://www.openstreetmap.org/browse/node/500915665
was part of two ways: 41085570 and 41085568
The first way is a complete forest polygon, the last one a broken one, so it was likely that the latter was causing the problem.
