[MOD RELATED] [S] Holiday stuck in calendar causing issues for new holidays

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.58.69.1010
What expansions, game packs, and stuff packs do you have installed? All of them.
Steps: How can we find the bug ourselves? Occurs whenever there is a holiday, sometimes when there is not. Traveling to new lots can trigger it.
What happens when the bug occurs? My sims holidays are all glitched up. It's not the just premade holidays (New Skill Day, Rebate Day) , it's the holidays I created, like Thanksgiving, Halloween, etc. There isn't supposed to be a holiday one day and it will say it's the holiday from yesterday. Or, it's supposed to be Christmas, and it will say it's Christmas Eve. And, every time my sim travels to a new lot, it will change. The holiday will disappear, or it will be a different holiday. I think the calendar may be out of sync with the week. Driving me nuts!
What do you expect to see? My sims able to celebrate holidays. Holidays falling on the correct day.
Have you installed any customization with the game, e.g. Custom Content or Mods? Yes
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure
