Not familiar with the specifics of your Navigator leveling system. But on ours, I have no problem resetting and starting the leveling process all over. It will just fine tune the level as needed.
We usually turnoff the automatic check of level, as the electric compressor kicking on to tune the level, spooks are dog. So pretty normal for us while in a location over a few weeks time, to manually turn on the leveling system to have it do the tuning for us periodically, then turning the auto-check of level off again.
Believe your coach was during the Monaco days, so you might also check with the Monaco owners forum, to see if Monaco had something unique that makes this not a good idea(?).
And, next time you're in for service, you might have that corner looked over for problems. Slow air leak? Leveling lever out of sync? Airbag problem? Etc.
Best of luck to you,
