Error in pin color change on map wiget

Hi, I am working with map wiget and show pins on map with diferents colors. If a condicion is true or false the color change. So it is work ok, but sometime these pins show a black color and in the infobox, doesnt show my variables. Which could be the mistake?

Hello there.
Is it the blueprint map widget? How did you manage your conditions, could you share a picture?
Maybe the condition is getting a third value, besides true and false. You could set an “anything” condition just to be sure.
