Mini catt’s new growth has only one leaf. Worry?

[Maru777]

Hello everyone,

I have this mini cattleya and I thought I was doing ok with it. It grew 3 new structures since I got it and they all looked nice and plump. The plant also grew more roots - it came with very few. So I was pretty happy but not this last 4th growth all of a sudden has only one leaf. All the other ones it grew while I had it have 2. Should I worry? What have I done to it? I did not change all that much they way I took care of it so I don’t know why it’s doing this. Thank you!
