Hello, I have a bit of a problem in Blender that someone might help me with 😃

To put the new decals, I open Blender, select the object I want to put the new decoration onto in the materials node tree, make sure that there's the necessary metal and bump maps (if needed) provided, but something odd happens. When I'm on Color Data, it shows grey pieces (even some non-custom decorations and dual moulded bricks) and when I'm on Non Color Data, it shows the right colours, only noticably lighter than they should be. What could be the cause of that?
