When viewing a completed interaction record via browsing the results from an Steps/Interactions ad-hoc query, you might notice that fields are missing.
The reason we see a difference here is because the user is viewing different interaction pages. When users browse to a constituent and view interactions they're using the ‘Constituent Interactions Page’ whereas in query the user is specifically selecting the ‘Interactions Page’.
Steps to Duplicate
1) From a constituent record, go to a completed interaction. 2) Notice that the fields: Subcategory, Contact method, Event, Expected start time, Actual start time, Expected end time, Actual end time, Time zone, and Location are present on the page. 3) Make a Steps/Interactions ad-hoc query containing only that interaction. 4) Go to Preview results > Browse [Query Results] > Interaction page 5) Notice that the fields above are missing.
