Hi, 

In the last couple of weeks a strange thing has been happening to our invoice and invoice items templates. Sporadically, the invoice template is switching from the normal jrxml report to a document called 1.pdf and as a result, it is impossible to print an invoice. The problem is resolved by uploading the correct jasper report again however it dettaches within a day or so. 

Any ideas - nothing that I know has changed.
