We backup our visualizations and dashboard from Kibana v.5.1 and restore it to Kibana v.6.2.2. Unfortunately, were getting some errors.

A field associated with this object no longer exists in the index pattern.
If you know what this error means, go ahead and fix it — otherwise click the delete button above.
Is there any way how to fix this? Thank you.
