Centre-Radius Circle Tool for Technical Suite 2019

Hi, could do with some help please. This is probably a very basic question, but we have recently upgraded from Technical Suite 2018 to 2019 and are now unable to use the Centre-Radius Circle Tool properly, we can select the function on the side bar but unlike the previous version there is no pop up window that allows you to type in the Radius value. Does anyone know if this feature is still available and if so where it could be found, whether we just need to tick/untick something?

Apologies for what is probably a very basic problem but it has been bothering us for ages!

Many thanks in advance!
