When Insight was installed it created Custom Fields for our Service management Project(s).
(both team managed and company managed projects are exhibiting the same issue)
This shows up as a field in the issue, which has a nice little blue "+ Link Asset" When selecting this is searches for assets but sees none.

How is this custom field, or Insight Schema/object configured so that assets can be linked to service tickets?
I can (and have) created a new custom field which works as expected.

But I am wanting to use the custom field automatically created by Insight
thanks
