Yearly Savings Confusion

I'm trying to alter my Car insurance goal, as I realise I've been saving less than will be required.

I need the money by the end of July, but this month I can only save £55 into the category, all fine, this brings me to £307 in the category.

However YNAB is saying I need to add £194 this month, and then next month, for next year, its saying the goal is to add £444 more? I'm confused as to why it's not just dividing the amounts over the 2 months, and then the next 12?
