Okay, this is within the course designer, Edit, Create/Add, Place Objects, Nature. After the patch, I find that I can not access anything but the first page of objects. In other words, I can't access Page 2 of Trees, or Pages 2 or 3 of Global Plants. Same with Create/Add, Place Objects, Buildings, Townhouses or City.
I have tried exiting the Course Designer and then going back in. And when that didn't work, I exited the game, and then re-entered. Still not working.
