Park Opening/Closing Times change but my pre-existing TP hasn't updated

So I have several TP’s created for 2/2-2/4 and I received an email this morning that the Opening and Closing times have changed for my parks. I noticed that for my plans the theme parks open/close times haven’t updated.

I’m also unable to manually update to the newer opening times. Will this resolve on itself or will I need to manually create new plans?

Maybe email -
