I don't understand why, for a first membership, when a member chooses the "Pay later" option s.he gets a new activity "Renewal" recorded once the payment is manually added by the admin but not if s.he just pays live with credit card?
It's not a renewal and I don't want this activity to be added. This is mistaking the reports for those who are really renewing their membership and need to be separately identified for backoffice purpose.
I don't have a special CiviRule that would involve this behaviour so I guess it's build in CiviCRM.
I'm using CiviCRM 5.21.0 on Drupal 7.67
How could I fix this?
EDIT 2: I've tried on a different CiviCRM/Drupal website and it ends the same. It creates an unwanted Renewal activity
EDIT 3: After a step-by-step comparison with the demo, it appears that when registering a member, CiviCRM creates an "Online or offline membership signup." activity that I don't see on the demo instead it creates a Pending membership coloured in red that is deleted after a payment. And when entering a contribution, it logically adds a "Renewal" activity. So now, it's more about why is CiviCRM creating this first membership and no more why I get a renewal activity. little step forward...
