When you display a save error in WME, please give us helpful suggestions on how to resolve the issue, not just a generic "check and try again." Check what? What are we looking for? How do we fix it? What is "modifying GuidanceMode? What are CS Lanes? Saying "Check and try again" doesn't help.

Example:
Modifying GuidanceMode is allowed only for CS Lanes
Suggestion: Check and try again
