Banded rows in Excel online not working randomly

Hello everyone,

One of my users stumbled on a weird issue with Excel online.

The banded rows are disappearing randomly when vieweing the Excel file.

Something like this.

Some cells have them, others have not.

The issue is only present when viewed with Excel Online for this specific user.

Opening in standard Excel works fine, opening as another user works fine.

This is not a browser issue either as the issue is present in Chrome/Firefox/Edge.

On the overall array, only 3 columns are impacted.

Two do not have any banded rows, one has some of them dissapearing randomly.
