I’ve bought this phal schilleriana as a seedling and I was so excited that it was finally growing a flower spike for the first time. But I think it grew a mutant one

I was looking forward for a bud to appear but now at the top of the flower spike what I see is a little leaf. Could this be a keiki or just a mutation that will die out? What’s going on with my plant? Hopefully it will bloom properly next time? Or is it doomed to just trick me?
