Room labels dimensions shown in decimals not fractions???

[Hannah's dad]

Hello,

I draw house plans for fun and have used Chief Arch. Pro 9.0 for almost a year and a half and still have issue with the room labels.
Every plan I make when I identify the room and the size pop up on the screen it says 12' 4.175" X 7' 8.453"/

What have I done? How can I change this??

Thanks

Tod
