Meshes appear through decals

Help and Feedback Game Design Support
#1

I made a room with tinted windows and I decided to add some plants inside for decoration. The windows use a decal for the tint and the plants use mesh parts. While I was editing the plants (making sure they don’t clip through walls and stuff like that), I was able to see certain parts through the window, even though there was a decal blocking it. Here are two plants showing through the window RobloxScreenShot20210912_175629683|690x333

Is this supposed to happen or is this a bug?

Is The Mesh Transparent set above 0?

#3

There are three mesh parts. Two of them have their transparency at 0.1 while the other one is 0.

#4

So I was playing with the properties trying to fix this and I accidentally discovered that changing the material to glass fixes this without changing how the mesh looks. It might still be a bug since this is really weird for me, but this is a temporary workaround.
