Not missing a thing. Dropping of the wing is normal in a rudder turn. If it didn't drop something would be unusual, especially in a Nexstar or other trainer. No shame in going around, good to know when it is needed. NOBODY greases every landing that I know of. Some are better than others of course. When vacation is scheduled, rain is also usually scheduled for me also. Is wing tip "thingamajigs" a new tech term? Their purpose was to make the center section of the wing stall before the tips and therefore reduce spin tendencies. Supposed to make the nose drop straight ahead when the center stalls. Many planes have a little "washout" built into the wing for the same reason or have other devices added (full scale and models). I don't like carrying mine more than I have to either.
Glad you are getting the hang of it, keep practicing the takeoffs and landings.
