I am new to the X-T10 and encounter a small problem: suddenly it proves impossible to choose any of the presets that should be available with ADV1 & 2. In the menu the "ADVANCED FILTER" option is visible but unreachable. Tried both auto and non-auto settings. What am I doing wrong here? STOP: I found out what was wrong - I should assign this function to one of the function buttons. I thought it was programmable by the dial on the back.
