Hi there @April_Fgt,
So, I think what's confusing you is that with your current set up changesetArray only includes values that have been edited, rather than your full row. In fact, in your second screenshot there is an edit only in status, therefore Container comes across as undefined, as this column is not being included in changesetArray (as no edits are present).
What you can do is enable the below option in your table:
This will include the full row, which will then ensure that any column you're referring shows the value, whether the edited one or the current data.
Hope this helps!
Best,
Miguel
