why are there two lines numbered 30?

In some documents, there may be two lines numbered 30 due to formatting issues or errors in pagination, such as when text is added or removed. This can occur in legal documents, scripts, or manuscripts where revisions are made. It can also happen in printed materials where the layout shifts unexpectedly, leading to duplicate numbering. To clarify, it's essential to review the context or accompanying notes to determine which line to reference.
