Foliage moves after saving

I have foliage painted on a landscape and some static meshes and when I save the project, the foliage moves away from the scene. If I move it back into the proper position and save it again, it moves farther away.

In this image you can see the foliage on the left side and the pivot on the right. The foliage will always be in that position (I believe that is 0,0,0) but the pivot moves when it’s saved.

I’m wondering if there’s a way to fix this as I would really like to avoid having to repaint the foliage. Thanks!
