When reimporting the model, the previously painted vegetation disappears

When I am about to re-import the model to update changes, the textures remain, but the vegetation applied with a brush disappears. The element is still as if it existed, but it is not seen in the model nor is it noticeable, and I have to redraw the entire vegetation drawing. Help.
