These things happen from time to time and they are a beautiful plant.
They can however be prone to being male, so keep a close eye on it.
I would also suggest transplanting soon, those tiny cups don't provide much room for root growth and plants can become dwarfed rather quickly in cups. This is also the most important formative time in establishing the plant, so the sooner she can grow without restriction, the better.
Hope this helps,........
