Describe the bug:

In my test site, the Overview card shows that there is 1 error, but there are no details about the error in the Overview card or in the Issues table. The issues table has only 40 warning issues. See screenshot below:

Steps to reproduce:

1. Connect Pinterest account, wait for syncing, then look at the stats in the Overview card and the data in the Issues table.

Expected behavior:

There should be explanation for the errors in the Issues table.

Actual behavior:

There are no explanation for the errors in the Issues table.
