The number next to any grouped folder shows how many promotions are in that group.
If you’ve selected any promotions within a group, you’ll see two numbers:
That number on the right, in grey, still shows the total number of promotions in the folder. But the new, blue highlighted number on the left shows the number of promotions currently selected that are in that group.
This number next to your grouped folder will also change if you’re searching your promotions, using the search field in the sidebar. In that case, the number that appears next to your group is the number of promotions in that folder that match your search results.
