How to remove user properties that have "$set" and "$setOnce" prefix

I have an issue where some UTM parameters have the prefixes "$set" or "$set_once".

I discussed with the team at Segment, which we’re are using to send the events, and they’ve since fixed the issue on their end.

However, the issue is still there on Amplitude's side. One suggestion the Segment team had was to remove the affected UTM parameters so that future events will be recorded properly.

How can I remove these UTM parameters? or is there a better approach to solving this?

Hi @Asoka Wotulo 

You can hide these user properties from the UI using Data to begin with. But since they are already ingested, they will persist on future events.

You’ll have to ‘unset’ these user property values via the Identify API call which should stop them from being seen on future events..
