Happy New Year Liz! How frustrating for you! There a a few issues/questions: Are you riding a 1x or 2x chainring set up?
Has the rear derailleur alignment been checked? (The dropout?) Are the two jockey wheels aligned? If you stand behind the parked bike, in the lowest gear, close one eye and imagine a line strait up and down where the chain comes up off the two wheels. If it’s cocked in any way, that can lead to the ghost shifts. It can also be the jockey wheels aren’t lubed or aren’t the proper ones for your shift system. Are you certain that the rear cable is free of any possible crimps, (like under the bottom bracket?) Do you have a kick stand mounted? If so, look carefully at the cables adjacent to the kickstand and that the cables do NOT touch the kickstand or its bracket. It’s often overlooked. Another test- grab the rear bare shift cable and see if that shifts and overrides the shifters. (You may need to put your bike on a stationary trainer). Last check- make certain you don’t have a modern 11-12 speed chain on the bike. It takes the older, wider chain on these wider spaced freewheels/cassettes. Good luck!
