Number pad option missing from SwiftKey "Keys" menu

Earlier there was an option to have number pad in rows of three, like 1 2 3 on top 4 5 6 in middle and 7 8 9 on bottom, instead of having all numbers in one single row. This option was available in the 'Keys' setting. Today, after a factory reset, I reinstalled all of the apps, including SwiftKey and I couldn't find that option anywhere! Please help me with this. Single row of numbers drive me insane.
