Bamboo invoice - View fix

I'm using bamboo invoice, which is no longer maintained, but I like it, so I will continue. However, something is wrong with the view system. When I click to view "all invoices", it only displays the last 5 months and of course, I just need it to show every single invoice, regardless of its status. It uses ajax, which I can't do, so I just need this view fixed asap. Please comment the lines that you modify with so that I can keep track of modifications, as I intend to make some further modifications in future. Please comment like this: //mod single line of code (); or //mod { multiple lines of code } //end mod [login to view URL]
