Dots Get "Stuck" at Top of Graph

[Stars]

When I make a combo chart (using vizlib), I overlay dots on my bar charts.  Usually it works great.  Occasionally, I'll open the app again and the dots will all be 'stuck' at the top of the graph.  What causes this?  Is there an easy way to fix it?  The data should be the same.  The expression for the dots is very basic, so I know it's not a problem with the expression.  Thank you!
