TextTag How to make ToolTip Work

The TextTag documentation shows :tooltip("Insert Tip Here") as the syntax for the tooltip

so I did

{{*Day_es_:signer:tooltip(‘enter a day’)}}

When I upload the document to the management center as a template, there is no tool tip.

I'm trying to get a description of what I want the signer to enter.  I know there are standard ones of company and title thay say enter your company name here.... but I can't get it to say what I want when I want it to say "Please Enter Day of Month"
