Single Select / Multi Select list conversion duplicates field (Behaviour) on Jira Server

[Peter Andréasson]

Hello Team,

I've have experienced similar issues as this ticket: SRJIRA-3771

Once we convert a field into multiselect using scriptrunner behavior we get this fields duplicated. See attachments.

Jira Server version:  v8.6.1
ScriptRunner version: 6.1.0-p5

Regards
