I notice there is a resolved issue:
Saved searches that include macros are sometimes not editable by
non-admin users. (SPL-49875)
We did have macro search in search terms. and macro search is made by admin and shared with everyone.
Then I tried it on version 4.3.2, I found I can replicate this issue!
Then I upgrade my lab splunk to 4.3.3. This issue is resolved.
I will update the main splunk from 4.3.1 to 4.3.3
After Upgrade to 4.3.3, This issue has been resolved.
