¡ and ¿ go at the beginning of sentences in Spanish, so we would normally expect the next letter to be capitalised

The example from that ticket was "¡Peronismo para te! ¿Peronismo para te?", using the sentence case mode gives "¡peronismo para te! ¿peronismo para te?" and using English mode gives "¡peronismo Para Te! ¿peronismo Para Te?"
