I observed that in GL>>Journal Entry, when I add a line to a journal entry the button "Post Transaction" disappear. Only the "New transaction" is available. If I click it, the "Post transaction" appears again, but if I click "add line" the button disappear again. Otherwise, I don't get to make journal entries. There's no errors on log.
I believe that maybe it be the source of problem with AP>>Invoices>>"Post Invoice".

Does it make sense?
