In Indesign 2020 when paragraph styles are based on other paragraph styles that are within a group, the based on area does not indicate which group the style is in, it only shows the name of the style. Which makes it difficult to know which actual style it's based on if you have multiple styles with the same name that are in various groups. Screen shots of Indesign 2020 attached and Indesign CS6 where it did show the group name in the based on area.
