Why the error when upgrade Splunk from 7.3.x to 8.1.5 on DMC Search Activity?

[dm1]

Newly upgraded Splunk to 8.1.5 from 7.3.x and seeing the below error message on DMC Search Activity:Instance

Multiple renames to field 'Type' detected. Only the last one will appear, and previous 'from' fields will be dropped.

Any ideas or suggestions on how to fix this ?

You can drill down into the search, and just remove the last rename. 
delete this  -  search_props.type as "Type"

If you take that off it will work without error.
