Qlikview - Combo Chart changes bar to line - Fast Type change is NOT selected

[mp802377]

Combo Chart

Nothing selected in Fast Type Change. When I select multiple filters it changes one of the expressions from a bar to a line

Dimension

     1. variable - $(vShowDimension)

Expressions

     1. Success - Sum(Success) - bar - Left(Bottom)

     2. Failed - bar - Sum(Failed) -  Left(Bottom)

     3. Average Failed - (SUM(Failed) / Sum(Failed+ Success) ) - symbol (no line) - Right(Top)

Style: Stacked. Now the weird thing here is, when I created a new chart and had the SubType selected as Grouped, it created a line for Average Failed. And still kept the bar for Failed.

The first chart shows where the SubType is selected as Grouped. You can see it creates a line at the Average Failed. The second chart shows when the SubType is selected is Stacked. You can see the Success bar has changed to a line. Also, I found this only occurs when the average failed rate is 100%. If it is any other number, there are no issues. You can see there are no conditions that say if this is this, than do this.
