Why do the task outcomes have to be in lower case?

Hi,

So I think I'm going a little batty, but for some reason, whenever I define the outcomes for a task, the outcomes are set to lower case, except the first letter.

So Escalate to John becomes Escalate to john. Is there anyway to stop this happening? Is this something I've done?

I'm using Nintex forms for Office 365 by the way
