Hi @anya.conti,
We’ve double-checked again and confirmed that this is a bug from our end. The fix has been implemented immediately, and it should now be working. Could you please help check it again?
For context, this regression came from our recent Dataset Field Tree improvements, which gives the users a cleaner hierarchy UI, smoother drag-and-drop experience, better search, and much faster performance on large datasets (announced here).
We missed this case of hidden fields still showing within the Custom Dataset view, and have been actively working on a fix right away after you reported.
Alongside this work, we also identified a bug where metrics with hidden: true are hidden in Custom view. Now they should be shown like other fields, for consistency.
Once again, we sincerely apologize for causing a big headache for your team. If anything still looks off, let us know and we’ll jump on it right away.
