Sales Tax Return Already Exists

Using QB Desktop Pro 2021, I am trying to file sales tax for the period. Filing sales tax for the previous period has been already done and payment to CRA is recorded in QBD. 

Ran "File Sales Tax" from Sales Tax menu, selected the agency and the dates, then clicked on "Print Return" to save a copy of the report before file the return.

Previously, I would click on "File Return" and then would select "Paper or other filing method" to save the report by printing as PDF. But this time I used "Print Return" button and then clicked the File Return button. 

The issue is that each time I click on File Return button, a warning window opens saying "A Sales Tax return already exists for the date selected. Please select another date." and I can't go any further by closing it.

Please advise what I should do. How this could be fixed?
