Column in Query Not Shown in Fields

[gbluestein]

I have a column in my query that I can no longer find in "Fields".  All the measure I created from that field are visible but not the field itself.  Can you delete a "Field"?

If you delete that column, the measure created from that column will have an exclamation point besides it as below. Can you see it in your fields pane?

Please also check that if you hide the column as following screenshot, you can check it in Data view.

If the column is not hidden, could you please provide the steps that how you create this column in Query Editor?
