Quite surprising scaling

I always use BS scaling feature with great success.

I have 2 setups: a 20L Braumeister I use for 19L batches and a 10L pot I use for 5L BIAB batches.
I start by composing the 19L recipes for the Braumeister equipment and scale them down to the 5L BIAB equipment.

Recently, I wanted to try a Corona recipe (sorry about that) and the following amounts of fermentables for 19L with the Braumeister

2.64kg Carared (which blindly divided by 4 would be 660g)
960g Rice flakes (which blindly divided by 4 would be 240g)
480g Corn flakes (which blindly divided by 4 would be 120g)

turned into

350g Carared
400g Rice flakes
250g Corn flakes

Quite surprising, innit?

Did I miss something? Are there special scaling phenomenons with flakes?

Thanks

Most likely it was trying to match the color of the beer which can be a challenge in some cases when scaling.  If you uncheck the box that matches color, bitterness and gravity it will do a straight linear scale instead.
