I'm not level shifted down or up, just at level 50 in Ul'Dah. I tried to look this up, but apparently my misunderstanding is so basic, I'm the only one who doesn't get it...
Thunder III is an automatic upgrade from Thunder I and simply replaces it. When you get synced down to below the level you are able to use Thunder III then it will automatically become Thunder I again. This will be the same for Thunder II and Thunder IV when you get them as a heads up.

Several other jobs have a few abilities like this as well. E.g. Whm Stone I, II, III, IV and Glare are all automatic upgrades of the same spell, Summoner has Ruin III and Ruin I paired as an automatic upgrade as well as Ruin IV and Ruin II paired, etc.
