Deleted, replace, moved location, different label, and even held my tongue at a new angle ... no change.
Might be my Nexus 6? I will check with my Note8.0 tablet... Nope, same there as well.
I will force a change in the data being sent from a float (Thanks ) to an integer and check again.
Also noted: When I set up the new label, there was a glitch in the options... but touching the appropriate blank spot did chose the proper gradient.
