It’s not you… it’s Gmail.
Within Gmail, when sending an email to a Distribution List, Gmail will not send the email to the sender’s address even if they are listed in the Distribution List. Unfortunately, there is not a way to adjust this within Gmail.
So, if you send an email to your team email address from a Gmail address, you will not receive a copy of the email to your own email address. However, do not fear your team did receive the email.
