are the fields you are trying to add UDM fields or additional/extracted fields?
@BrianK Thanks for your reply
I don't think so - here's an image of the UDM lookup for the field - it doesn't say "enum" per se but it does come up as a result for UDM lookup on values "enum" (image)

Here's an example of a UDM line for a value also in the the same UDM field(s)

...and it does exist in the raw log, although there does seem to be some enrichment - it's put in the form of a sentence

thanks again
Did you find the solution?
i have this question too.
I can see the UDM contain the information i want but unable to add in the event table!
