Shared-to Person can't access

Shared-to Person can't access

In my application, I have an "Inactive" tab, that I have no issues with, but a person I have shared it to, while able to get at all three other tabs with no issues, when she goes to the "Inactive" tab, it gives an error retrieving data and just tells her "Failed to add data" if she tries to add anything. We have already cleared her cache and reboot her computer, but she has the same problem. Any ideas?
