Preventing building of all schemes when running

I have a workspace / project with multiple schemes. When I go to run my current scheme, the middle status text bar shows that Xcode is going through each scheme and building it. I am trying to reduce build time and it seems that it is cycling through each one (sometimes endlessly).

Running Version 9.1 (9B55).



See the following video, it seems to repeat and start over from the beginning for the multiple schemes:
