Calendar All Messed UP

Hi, moderators, this may be in the wrong section, I don't quite know for sure. Please move it, if so.

Just yesterday when I was checking my game calendar, I noticed something a bit off.  I have Get Famous and am used to the Starlight Accolades Show showing up on each Sunday. I'm on Saturday of the game, and the next day it shows, but the rest of the Sundays don't have the event flagged.  To be honest, I have not played an earlier save to see if the show goes on, as usual, but I am very bothered by the fact it isn't listed for the rest of the game-year.

True enough, to save a bit of time after a needed rollback, I switched to a 7-day Season, but once I got to the next week I returned to the 14-day season.  If something happened during the switch over, I surely didn't notice it right away.

I have searched through several of the earlier saves (I always do a Save As at the beginning of game play) and all of the most recent ones are missing the event flag for the Starlight Accolades. Is there a way to fix this, please?

It is my hope to solve this problem before the Jumbo Patch hits tomorrow, if possible. Otherwise, I will have to return to a much earlier save wherein I have no identifiable problems with the save. But that takes the teen twins back to their toddlerhood. Before I can share anymore updates, I'll have to play a lot, in order to catch up, lest the updates mess with the current timeline of events. Oi.

Any and all help is appreciated. Please, and thank you, in advance.
