It's an F1 that went OP and is not all that well documented. The different sizes could be part of their mutation - I don't know? I have two plants isolated and will be able to tell you more within a few weeks.
The fact that they are still PWR could be that this is the next stage in how they are growing out. I have a lot of thoughts, but no formal education when it comes to gardening.
