Interesting new leaf on dreadlocks

[junglegal]

1/2 an oak leaf appeared on newest growth. Telling of it's parentage? This plant is several years old. Bought it at Fairchild when it was the newest rage. It's always struggled a bit for me but is finally coming into it's own although I should be giving it more sun. As soon as I thin the dypsis, that should be solved.
Anyone else have them do this?

That is funky. Mine doesn't do that.
