I'm trying to do a Trailhead for learning Lightning Components titled "Prepare to be Object Agnostic" - the exact instructions are listed below. The problem I am having is when I click "New" to seemingly add a new value to the Picklist, instead of a simple data entry task the "Object Manager" is opening!?!?  I don't understand why - is there a glitch in the Trailhead or am I making a Newbie mistake?  Please advise - thanks! 

Trailhead instructions:

From the Custom Fields section of the Indicator Badge detail page, select the Badge Color picklist.
Scroll down to the Values section and select New.
Enter RosyBrown as a value.
