Geo coordinate Custom projection library Not Showing

Dear All,

I want to export horizontal alignment to Google earth. I have copied  the custom GDM.dty (for Selangor, Malaysia) file in C:\ProgramData\Bentley\MX V8i\WorkSpace\Standards\datain then added to  MS_GEOCOORDINATE_USERLIBRARIES (UCF) in workspace menu. After that I restarted my MX road_SS-2

But iam not getting the drop down (sub options) to select the Coordinate system. Requesting you to please suggest me some solution to resolve this issue.

Thanks in Advance
