V 3.6, sent campaign and got error and it kept retrying. Now cannot find record of campaign

Recently upgraded to phplist 3.6. I created a campaign and selected groups to receive the email. Initiated send and it took awhile and then indicated an error and waited only about a second and tried to resend. First time I didn’t cancel right away and it tried 30-40 times before I canceled. I then suspended it and marked it sent. Now I am unable to find any record of the campaign, although there is a record of the send in individual records of it being sent.
