Hello, I’m new to bee keeping and over the Christmas break I harvested my first 4 jars of honey. Sadly, stupidly, I didn’t close the cells completely and honey continued to run out 
I cleaned up all I could see and today I discovered some in the tray under the brood box. I’ve cleaned that up and everyone seems happy, still working away but WHAT do I do???
Welcome to the forum, Kerry.
Don’t beat yourself up. Beekeeping is a forever learning experience.
You seem to have the misconception that closing the cells or returning them to the normal position stops the flow of honey. It doesn’t. When you turn the lever to “open” the cells, the wax lining of the cell walls are torn apart, causing the honey to flow to the back and down to the channel at the bottom, then out the spout. If your “close” the cells before the honey is fully extracted, the honey will continue to flow, but instead of out the spout that’s no longer there, it flows through the small slot near the cap into the brood box.
Another common problem can be leakage. If there were any cells not capped, the honey can run down the front of the frame instead of through the back. The leakage drops through to the brood box below. This is the worst outcome because now honey flows over the brood and bees which can drown or suffocate them.
Also, opening all the frames at once can cause flooding with a similar result.
Next time, allow every drop to flow into your jars. Open 25% at a time to prevent flooding. When the first 25% slows down, open the next and so on.
You’re not the only new beekeeper who’s experienced this situation and there’ll be other mishaps. Press on, ask questions. It’s all part of the process.

Thanks for your reply.
The brood box seemed ok when I checked it the next day so fingers crossed
I’ve certainly learnt a valuable lesson
