Materials automatically get renamed in all caps

i’m getting the refresh case sensitivity failure error and i noticed that my materials get renamed to be in all caps, but not the .meta files.
is there a reason “Floor” gets changed to “FLOOR” for example, and is this what is actually causing the error?

Same here on different unity version and projet pretty annoying anybody come with a solution for that ?

Same here… but a way to fix it?

still in 2018.1.4

Import a load of materials into a new project, and some of them will randomly be renamed into all caps.

Still in 2018.2.0f2
