Nvidia Inspector anisotropic filtering won't work

Hello guys, i did a fresh install of my FSX due to some problems i was having after thousands of add-ons installed. I decided to start everything again and installed just the essential. The problem is i'm having some troubles with using the Nvidia Inspector. I used it before and applied the same configuration this time but the anisotropic filtering seems to not be working. i've attached two images, one of the FSX running and other of the Inspector configs to see if someone identifies the error.
