Hi @Natalie Soto,
Do you invite user to the SharePoint site via the "Advanced permissions settings" page like the screenshot below?
You can click "SHOW OPTIONS" to expand the settings and select the permission level you want when sharing.
To change the permission level for existing access users, you can go to the Home page >> click the gear >> Site permissions >> Advanced permissions settings >> Check the user >> Edit User Permissions.
Hope my answer helps. Please comment below if I misunderstand.
