Update Operation sequence of a work definition through spreadsheet

We are trying to update a Work Definition Operation sequence of an existing work definition through a spreadsheet. We have enabled the Redwood UI for the Work Definition landing page as well. We have the spreadsheet downloaded and when we update the operation sequence in the spreadsheet and upload, the record gets submitted successfully but the UI is not changing to reflect that update. Is this sort of update supposed to be working through the Work Definition spreadhseet?
