Bump on bubble tip anemone?

Anyone know what this is?? White pic is lights off, always shrivels at night. Blue pic is during the day the next day it’s still opening and looking good so I don’t think it’s anything harmful I’m just curious as to what it is

That’s kind of what it looks like. I guess the best way to describe it is like a wart. Not sure if it’s another bubble tentacle growing or something else?
