I recently migrated a site from SP 2013 to O365, when I goto the permissions page (_layouts/15/user.aspx) and open up any group, I can see that the users are present in the group,but the title and description fields are not populated.

It is showing up in the 2013 site, but its empty in O365. Delve and Azure AD seems to have the title and department details.

When I add a user who has title and description on a different site to this site, the fields still don't show up. Does it take time for the user profile details to show up?

Any insights on what the issue could be?
