Material file name not match???

Hi all.

When I’m click static mesh to open up editor but I notice on LODO details panel shown material file name are not same as Details panel materials name on list. I thought it supposed same material name ?? See images below, Can you tell me what I’ve gone wrong?. How can fix all each static mesh item correct way match.

Regards

The little yellow arrow is indicating that the value in that material slot is non-default. Chances are you’ve overridden the material slot with another material. Hit the arrow and it’ll pop back to the one you have in your static mesh editor.

Oh I don’t know that I’ve done overridden the material slot. This is my first time try out using Unreal Engine 4. So I gonna have to double check whole walls all over again.

Cheer thank.
