I tried this before (with some points only) and I got tricked by a small flaw of the software.
If I
a) create a list (this new view you mentioned) with all waypoints
b) select all waypoints with the button in the top bar
c) delete this waypoints from the list
d) go back to the main view
then I can see all waypoints again. It seems that the main view is somehow cached.
If I
a) end Oruxmaps
b) unload Oruxmaps in the app list
c) open Oruxmaps again
then the waypoints disappear forever.
