When you've submitted on an opportunity that accepts Alternate Submissions, you may notice that you still have an alternate submission in progress.

You may have accidentally created the alternate Work-in-Progress submission if you started your primary submission and then tried to continue it at a later point in time. Conversely, you may have started an alternate submission intentionally but have decided not to go through with submitting one.

In either case, there isn't a way to remove the Work-in-Progress submission, however, this will not affect your main proposal or what you've already submitted. Only proposals that have been officially submitted will be viewable to the Project Owner when the project closes.
