How to modify the Transcy app translation for a contact form?

Hi,

we are translating our Shop to the english language with the Transcy App and looking at the translation of the Kontaktformular. In the screenshot you see that the “contact form” should have a capital letter at the beginning but i dont find any opportunities to change it on transcy or in the theme code (i think i overlooked something).

Can somebody tell me where to find the translation in Transcy or inside the code?
