How To Process Each Line Of The Text Prompt
The dropdown How to Process each Line of the Text Prompt changes how WanGP interprets multiline prompts.

The UI shows these choices:

Each New Line Will Add a new Video/Image/Audio Request to the Generation Queue
Each Line Will be used for a new Sliding Window of the same Video Generation
All the Lines are Part of the Same Prompt
Which wording you see depends on the current model and whether it outputs video, image, or audio.
