Mailalert module weird behavior

[kiwee]

Hi !
I have a website on Prestashop 1.7.6.9. I installed mailalert module to receive new order and low stock alerts.

No problem for the new orders alerts, but the low stock emails are not sent correctly :
- Both emails (new order and low stocks) must be sent to the same email A
- I set A as the recipient in the mailalert module parameters.
- No problem for the new order email, they are sent to A
- The low stocks alerts are sent to every member of the team (anybody with an admin account, no matter the group SuperAdmin or Commercial). It is a real problem for me. Also, the email template used it the Prestashop one, not the module template.
- I tried to add a second email B in the module parameters : it solves part of the problem ; the low stock email is sent only to A and B (most of the time, when the stock is 0 the email is still sent to everybody). Also to A and B the email template used is the module one.
- My problem is now, B receives the new order emails too (of course), and only A must receive that email.

What can I do to make sure all emails are sent to A only ? Maybe I just misconfigured something ? MailAlert has been updated.
I looked for an anwsers on many forums but I couldn't find any similar problem.

I have the same problem on another shop in 1.7.6.

Thanks !
