A badge icon doesn’t appear if the path added to Bandizip’s accessible folders list overlaps the paths used by other Finder extensions (cloud sync apps, mostly).
This usually occurs when used simultaneously with cloud synchronization apps such as Dropbox, OneDrive, and Google Drive that use Finder Extensions.
It is assumed that according to the order in which the extensions are applied, only the badge icon of the last extension is displayed. As Bandizip doesn’t use any badge icon, the other badge icons aren’t displayed either.
Although there is no general solution for the problem at this moment since it is caused by the limitation of the Finder itself, we are finding out if there is an alternative.
