We are using Contexthub on AEM 6.4. Found that when authoring a targeted component for each segment, the style that was selected from the style system is not carried over to the segment-specific version - it only shows on "default". The style system option is also not there when in "Targeting" mode so there is no way to set the style for each segment. Aside from this, the i18n can only be seen on the "default" segment/experiences. For other segments, it always shows the English labels.
Has anybody encountered this behavior? Any help, insights, or suggestions are all welcome. Thanks in advance.
It is not possible to use the style system in the targeting mode. An alternate way to achieve that can be by creating the Experience Fragments  with different style options and then target using those Experience Fragments.
