Hello @BARBARABUSCEMI,
Would it be possible to share a screenshot of the issue? That little eye appears in a few places.

If you have an eye next to Grades in the navigation menu, you can fix that by going to Settings --> Navigation and enabling the Grades area. Don't forget to save the changes to navigation with the button at the bottom of the page.

If the eye is at the top of a column of an assignment in the Gradebook, you can click the three dots at the top of the same column (that appear when you hover over the top) and select Post Grades. You must post to everyone for the eye to go away.

If the eye is next to the grade in the Total column in the Gradebook, that indicates that there is an unreleased assignment grade. You need to go back through the columns and determine which one has not had all grades posted.
I hope that helps.
