From the the pictures, the anemone is definitly distressed. For an example, the tentacle lenth and disappearnce of the verrucae/fading is not normal seen in an established mertensii.
What is the alk, CA, and Mg levels? Again, if it was my anemone, I would get some new test kids and double check just to be sure.
I have never found an anemone safe butterfly, particularly in a same tank with an already distressed anemone.
I am not sure of the lighting issue because mertensii mostly from deep water and I have never seen mertensii in less then 30 feet deep, even in extreme low tide. A chronic insufficient lighting will produced browning not fading of its coloration. Bleaching, fading of the oral disc/tentacles, and verrucase mostly, happens in an acute situation for this specie. Just my personal observation, good luck.
