I recommend adding the Sugoi Translator Toolkit endpoint to the game (for using the Reipatcher auto-translation), then running Sugoi Translator alongside. Better translation, and has configs that can make it a lot faster too.

Seems like single calls of long text to translate don't work overall in Reipatcher, personally I'm using the Sugoi Toolkit Endpoint and it still doesn't work (good example of not working: Rank E exam battle, the enemy Master's description).
