What version are you in?  Can you provide some screenshots of your design (how the dropdown is configured) and the values on the clipboard?  -  It's not clear what you mean by "getting standard value on clipboard."

Hi Vineetha,

What you are observing seems to be an expected behavior, as the intention of Prompt List is to present the user with user-understandable values but store the standard values internally.

You can refer to the below help. or attachment

To add, if you still want to store the prompt value on the clipboard, you may use Local List instead, which store the same value displayed on UI. Else configure an on change event which overrides the default standard value with prompt value.
