Sometimes 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 a 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 for reasons related to transparency, however this will not affect your main proposal or whatever you've already submitted. To expand on this, only proposals that have been officially submitted will be viewable to the Project Owner when the project closes.
