The issue is related to User custom column reference values.


As per best practice suggested by Product Management Team it is recommended that

  • For values that are never reused/unique to each user, do NOT create referenced values.  These should be free-form text entry. In this case, do not use Referenced custom column.
  • For values that are reference lists, only use dropdowns when the lists are short (any more than 100 is not a good user experience).

Workaround :

To update drop down property, please use below steps:

  1. Login into LMS as Admin
  2. Go to System Admin -> Configuration -> Search Selectors -> Select Records per page=All
  3. Search for search selector "Custom Column User reference" and click on Edit
  4. You will find the configuration in the search selector  "dropDownEnabled"SearchSelectorConfig.png
  5. Update the configuration to change its value from true to false.    dropDownEnabled=false
