How to delete call group - android 6.0.1

[AC Question]

I have a Galaxy S6 Edge. I can create a call group, but there's no way to delete it (that I can find).

I discovered that I can delete a group by going to Edit, then deleting all the individual members, then pressing More. However, I want to delete an old contact list that has about 1800 members. There's no way to do a mass deletion -- I'd have to delete them all one at a time...!!! Hopefully, there's another way. David
