@Marie_Poutakidis - welcome to the forum! I think this is a separate issue from the OP. For what you’re reporting, I think this stems from a recent update that allows projects to be shared with multiple teams:
What is your desired outcome? Is your project currently public to your organization? If you just want to “move” it from one team to another, you can go into the share settings (blue button near the top right where you see the project members’ avatars) and add the new team and remove the old team.
