I just figured it out myself, it all matters where the output is on the GUI, for example, the "Basic Factory" has 3 outputs on the bottom of the GUI, so you need to put the import bus on the bottom, and the 3 inputs at the top, so place the export on top of the machine. Think of Export Buses as exporting from your ME system and import importing INTO your ME system.
