New stem growing from old stem node, where to cut?

[chunkiepixie]

Hello! I've had a Phal orchid for almost 6 months, it did great and bloomed wonderfully through winter months! I was waiting for the last flower to fall before cutting the stem back, but new stems started to grow out of nodes before that happened.

I've never had that happen before, so wasn't sure where/if to cut. I thought it was another flower, but it has stem nodes.

Thank you in advance for any advice! This was probably a really basic obvious Orchids 101 thing. But I couldn't find advice EXACTLY for this when I looked. I tried!
