Guideline Colours when Printing

We have major inconsistency with the colour of guidelines when exporting or printing. When designing folders or other die cut items, it is often useful to export or print proofs showing the guidelines. However, the colour that they print or export in seems pretty random. I have tried setting the guideline colour in the Object Manager, as well as colouring the actual lines, but more often than not the printed or exported lines do not match. I've put a screenshot showing this. Anyone else finding this?
