IK Retargeter Window settings

I’m part of a project using diversion for file control, and after someone’s commit, my IK retargeter window looks like this, I’m trying to get it back to the default workflow / settings, but I’m not seeing anything online that covers this.

It appears that this has effected all my projects in 5.6, and I redownloaded and installed 5.6 to see if that would clear the issue, it has not.

Any help would be appreciated.
