I am on the 3rd challenge of the lightning connect project on trailhead. I have followed the instructions as stated, however when i try to create am indirect lookup relationship between customerID and account, account ( nor any other object)  does not show up on the drop down list. 


Quick Start: Lightning ConnectCreate an Indirect Lookup Relationship 
 

I can not checked this challenge although I did create The first Account ACME with a contact, then I create the second account and I did create a contact Role John Smith from ACME account.

Why Can't the contact role be found?
