Does any one know why I'm getting, what looks like version numbers on my Workflow?

unknown

As you can see I'm getting an number on this bad boy - and its annoying me to no end? 

Full work flow below.

 

I'm hacking my way through a full company workflow update and these little things are starting to build.

Would I have to delete other versions or variations of this workflow?
