When the script has too many revision marks, a production company may decide to send out the entire document with all the numbers reverted to normal numbering.
To do this with Screenwriter, you need to step back, undo-ing one or more levels of Locking.
Under the Format menu, select Element Styles....
Click on the Locked Scripts button.
Select the level of locking lower than currently set.
For example, if you have Multi-Locked Scene Numbers but only want Locked Scene Numbers—with all the Multi-Locked A-Scenes (64A1, for example) renumbered to be normal A-Scenes—uncheck Multi-Locked Scene Numbers by checking Locked Scene Numbers.
NOTE: If you unlock either a script's Page Breaks or Scene Headings, all of the appropriate A-Numbering is completely and permanently lost. That's why it's important to make backup copies of your scripts at least daily.
