[4.9.1] Procedural Trees Not Showing Up

I am using the Procedural Foliage Volume to place trees in my world. But after moving the project to version 4.9.1 the trees no longer show up in the editor. They do on the other hand show up when i play the world. In 4.8.3 I didn’t have this problem at all, The Trees showed up in the editor and in the game preview. ** Resimulating the volume doesn’t fix anything either and in the “Show” tab, Foliage is set to be on. **

Any thoughts?

I managed to solve this issue by migrating everything from my 4.8.3 version into a blank 4.9.1 map.
