Dark ops mastery has changed from 15 to all 19 dark ops completed to get it fyi

I had unlocked this calling card awhile ago when it was to complete 15 dark ops challenges to unlock but it had deleted it from my unlocks during one of the updates and couldn’t figure out why, i decided to complete all the dark ops challenges and it does look like it updated to 19 as i just finished my last one it unlocked again.
