There is an issue with the following config properties:

out_bound_roll: 
out_bound_pitch: 
out_bound_yaw: 

For example, to get a value of 45 in the application one must set the config file to a value of 13.5

If you then change another property in the application it will overwrite the 13.5 with 45 in the config. When you next start the application it default to the maximum of 178.5. Finally it will be stuck at 178.5 (it will read 178.5 in the config, and in the application - I guess this is just the maximum value).

As a workaround you can make all property changes in the application, then manually edit the config file afterwards. As long as you do not change the properties from inside the application then you will not have to keep changing the config.yaml
