'[Ad-Hoc Information Query].[Cross_Query].[CASE_DT_ID]' Error

 :) :)
I'm getting an error when I drag a column from my right panel in Workspace Advanced. I get the same in Query Studio. I can't find the Relationship in my FM Model.
Any suggestions?

QE-DEF-0030 Expression parsing error.
QE-DEF-0359 The query contains a reference to at least one object '[Ad-Hoc Information Query].[Cross_Query].[CASE_DT_ID]' that does not exist.

Is there a way to Search in FM Model to get  '[Ad-Hoc Information Query].[Cross_Query].[CASE_DT_ID]' ? So, I can get rid of it.

I used to have a folder in FM Model and therefore available as a part of Package but deleted this folder.

Thx so much.
