Anemone Tentacles turning white

[150 Gallon Reef]

I have a 100 gallon reef that has been setup for over 4 years with reef breeders LEDs above it. I’ve had my Sebae anemone for a little over a month now. Seems very happy. Moved around the sand bed until it found its spot and has not moved since. I spot feed it at least once a week and puts food down like a champ. Today I noticed a few random white tentacles on it. I’d say probably 6 tentacles in random locations on the nem, are white. Some looked normal size and others looked shriveled up. Does this happen sometimes with random tentacles? Do anemones drop tentacles sometimes? It’s very strange and would like to take care of an issue before it gets worse.
I do have a rock anemone on the other side of the tank, which looks happy and healthy.
I marked the points where the tentacles are white. Not the greatest photos but did the best I could.
Any help is appreciated
