Custom Sign up: Approved users being asked to confirm email

I have a custom sign up form.

Users either auto-approved or approved through wixUsersBackend.approveByToken are still being asked to confirm their emails.

These users are already shown as Active in Members collection as well as Members app. Still they are being asked to confirm their emails.

Additional issue with the same function: When using auto-approved setting, not all members are being asked to confirm their emails. If a member was registered in the past and was later deleted , such members are being asked to confirm their emails. On the other hand, if a member was never registered in the past, such members are not being asked to confirm their emails.

My Questions:

  1. Is it possible to turn these emails off?
  2. Is it possible to edit the design of these emails?
  3. Is it possible to send these out to all members signing up on the site instead of only to the ones who were registered historically and were later deleted? (when using auto-approved setting, and not through approveByEmail)
