A BUG with the landscape paint tool and foliage tool

I migrated my map to a new project and when I did The foliage and Grass on my terrain disappeared. when I tried to go repaint the foliage and terrain, the tool is simply not working, example: the radius of where your painting doesn’t show up and you cannot paint or add foliage… but when I go to the project that I migrated my map to the paint and foliage tool works as intended. Idk how to get it to work on my original project and I need it to because I’m afraid the project that I migrated my map too might be missing some important files or something I need.
