TOOLTIP: Display error on server and new desktop version Jul 2018

Tooltip was working fine until the July 2018 upgrade.

This was used in a basic way- age average was dropped into a tooltip. in a line graph using year in the legend to give one line per year, the values displayed as expected. Hovering over the line at a particular point showed the total for each year and the age average for each year.

The visual has axis of month, legend of year, values as a total and tooltip as an average of a value (customer age)

Now, on the server and on the Jul2018 desktop version update, this is not working. only one age average is showing, not age average per year as expected. Also for some strange reason, the earliest year is displayed as year.

(0 used as default number for display purpose only)

Working previous version hover display, selecting a particular month:

year 2013

  2013 0,000

  Age avg 00.00

year 2014

  2014 0,000

  Age avg 00.00

year 2015

  2015 0,000

  Age avg 00.00

New version now displays
