Is there a way to make surface appearances not dissapear when im far away?

[Iki_GN (iki)]

Hi, I was trying to make a tree, it is made of 2 meshes, one mesh is the trunk and the other one is the one that contains the leaves. When I imported it to roblox I added a Surface Appearance to the leaves. They looked fine, however, they dissapeared when I went far away, they only look fine if Im close, how can I fix this?

Edit:
I made another tree and this issue doesnt happen in that one, why??? How can I fix my previous tree?

try reuploading it

also the white lines that are around your leaves can be removed if you want. Try PixelFix
