why are my stacked column chart labels formatted differently?

[db042190]

Hi, these 2 stacked column charts come from essentially the same data.  I checked and double checked the data labels settings in the formatter on each and they seem identical.  But as you can see the top 1 displays a black background behind the label and the bottom one doesnt.  Even after the report is published, i see the same effect.  Why is this happening?

thx Ray.  The first image below shows those attributes for chart on top.  The second for chart below.   The 3rd shows a very suspicious thing in that the top one wont allow me to  change the data label colors to white.  When I do, it flashes and flips back to black even if i pick orange or something else.  The bottom has no problem switching to and staying white.

embarrassing.  The top chart had a different viz chosen, specifically "line and stacked column chart".  It was hard to catch because this viz doesnt draw a line even though its description suggests otherwise.  I show before and after below.  This is especially important because when/if pinned to a dashboard, overriding themes makes these numbers almost impossible to read in this tile.

Chart on top has background "On" or without a 100% Transparency color in the Data label, chart below surely has it turned off or with 100% Transparency.
