Display of the sender from google groups

Hi. I need some advice. When an email is sent to a Google group and then forwarded to a user, the user’s name doesn’t appear, only the group’s email. It seems to be an issue with the senders from the domain. Previously, the email client at least displayed the sender’s name via the group’s name. This is no longer working, and it’s difficult to search through emails now. Thanks for your help.
