I imported a HUD from Content Examples and the material gives errors.

Like the title says, I have imported the material and the texture into my project but it does not seem to work. i get an error. As you can see bellow, I get an error message. I also tried replicating the material into a new one. Same thing. I just cannot choose Linear Color no matter what texture I use. What could be the problem? Is the example outdated? I’m using 4.4

OK, I fixed it. Appearantly the problemw as that sRGB was ticked in the texture properties. After i unchecked it, no problems.
