DataLinkID Map Tip Bug? [HTML5 2.12]

Is anyone else seeing this or am I doing something wrong? I have done this before easily by adding a data link then adding to map tip using the token.

 

I got a 1 to 1 = Yes

 

I see the data linked in the feature details panel = yes

 

Tokens in Map Tip:

 

{folders.Folder} <---Doesn't show. No token warnings. If I change to {helloworld.Folder} it gives token warning.

 

{Tract_ID} <--Shows as expected.
