sharepoint online – Links in Team Site Left Navigation Column Only Visible to Site Admins

I have a SharePoint Online Team Site with multiple links in the left navigation column that only the Site Administrators can see. The only customization on the site is a script editor web part setting a background image. Site Owners and Members only see the “Home” link in the navigation column. I’ve completed the following steps to resolve this issue.

  1. Activated the Site Collection Features > SharePoint Sever Publishing Infrastructure and corresponding Site Actions > Manage Site Features > SharePoint Server Publishing features;
  2. Verified the ‘custom script’ and Quick Launch settings are enabled; and
  3. I’ve removed and re-created the navigation links.

Nothing has affected the visibility for Site members. Has anyone seen this happen before?

Thank you in advance for any assistance,
