I'm wondering if anyone running AutoCAD Mechanical 2017 has run into the following issue;

When I use the AM Detail command and change the options under the settings tab, the changes will take affect in the drawing until I close the drawing and re-open it (yes, I am saving prior to closing the drawing) and the AM Detail reverts back to the default set-up. When I was using Mechanical 2015 and used this command the changes saved with drawing and remained associated with it. I have gone in under options to the AM:Standards tab and changed the settings under the Standard Elements, however these changes do not take permanent effect and revert back to the default settings after the Options have been closed. Is this an issue that AutoDesk has not addressed? or is there a way to make the setting changes stay associated with the drawing? or has no one come across this problem yet?

Thank you for your help in advance.
