Cause

There may be an issue with the web browser cache.

Resolution

If possible ask the user to open a browser in Incognito mode to log in and see if mappings display in the Choose Document Type list.
If this works we would like to coordinate a time to have a CM Development Engineer conntect to troubleshoot browser caching issues that occur after a CM update. Please create a case through the Portal.
If the above is not possible, on each users' workstation, clear the browser cache, specifically for a duration of 'All Time,' for the designated browser being used.
