[PRO Export] - print ready files go in dropbox without order number

Does someone experienced the following problem with the Pro Export addon and Dropbox - When the files are being saved to dropbox - some files for some orders (completely random orders and files) are stored in the dropbox account, but they are not grouped in a folder with the order number, neither the filename contains the order number, rather the files are being saved to a folder named 0 with some random numbers. This makes it almost imossible to find the corresponding print files for the specific orders.
