Pots Close after Withdrawing?

So I’m trying to learn pots. I setup an Electricity bill pot and put some money into it. Then I moved it out of the pot so I can pay the bill but now my Electricity pot is closed and I can’t reopen it to add more money into it for next month.

Where did I go wrong?

I just tested this with a test pot and that didn’t happen to me. I moved in $5 which fulfilled the requirement. Then I moved the $5 out and the pot is still open.

Weird! I tested again with a new pot and now it works. I’m not sure what I did that it told me it was going to close it. Maybe I locked it?

Yeah I’m not sure, I haven’t tested locked pots yet.

If you locked it you can’t withdraw but you can still add to it.
