Hi Community. Thanks for your help. Every time, I print through a printer connected with POSBox, it prints two receipts- one with correct data and the other with 0 value and no product. This is the extra receipt that always comes out: https://www.dropbox.com/s/1r57sjc6vcw2xhc/Receipt with 0 value.jpeg?dl=0. 

I have Community Version 10 and I updated to latest nightly on June 3.
