How can I make Freeform stop capitalising words?

In theory there are options in Freeform to make it check spelling, or not do that, and to autocorrect it. However, I just cannot make it stop capitalising first letters. Even when it offers me the option to undo it, as shown below, often it sneakily redoes it later. Although I would love a Miro look alike that works offline, which this seems to be, this behaviour getting to be a deal breaker for me. Can I make it stop? tx
