2 of my ENS domains sold for free, bug??

Yesterday I modified the prices of two of my ENS that I was selling, pickpock.eth and bluejack.eth. Both prices were at 0.2222 and I put 0.222, signed the update with my wallet and quit the page. Today morning, I realize that both of them were sold to 0 ETH, and the history said that I put a price of 0 ETH yesterday...

So I assume there is a bug somewhere, because I tried to modify the price of another domain to 0, and a popup says "Do you really want to sell this for zero?" and I never never saw this popup yesterday so it was not a mistake from my side.

The only thing I can say to help to find the bug, is that my Internet was very very slow yesterday when I updated the prices, so maybe the page wad not fully loaded when I updated the prices, and it trigger another function to sign the contract or something?....
