The reason why the instructions do not match is due to Leapfrog not supporting Repetier Host anymore for the past two years. The only reason those are still up are for the customers that have been using Repetier Host before it was dropped.
So I would suggest using Simplify 3D instead.
Print settings in the Creatr Software can be directly updated in under 'print'.
The latest Simplify 3D profiles can be downloaded using the following links:
Bolt - Simplify3D settings
Bolt Pro - Simplify3D settings
To use the profiles, choose File, then Import FFF Profile and be sure to select the correct profile in your process. You can also watch this video.
