Leaves growing on Phal nodes while in flower??

[Elizadoo]

My 1st post, and I'm a kind of newbie.

I recently purchased a Phal at the grocery store because I have never seen one in bloom with leaves growing out of the nodes. The largest leaf is about 3/4" while smaller ones are 1/4". They don't look like the pictures of keikis I've seen online; they are more like "wrapped" around the spike, as opposed to growing like a root out of the spike.

Is there anything special I should do, once the flowers (not in the photo) die? Are these leaves indicating any problem with the plant?

Thanks for any help.
