Resolving Object Link not Appearing in Excel Export

I occasionally get these and usually ends up being a workaround. Sometimes when I submit it to workfront support they tell me to create a second report and that's how we find out the first report got corrupted. Other times the workaround is to use a different displayformat or a valueexpression instead of valuefield.

If you share which specific field you're using, usually one of the more helpful posters here can coach you through any further and more targeted troubleshooting. But hopefully the more general advice above is also helpful.
