Update: Facebook provided a fix to solve this issue that was coming from recent changes in APIs
There is a known bug right now with AdEspresso during campaign creation:
Any interests you use to refine the campaign's target will no longer be visibly applied to the audience.
This issue is being worked on by our team. Keep in mind your actual audience size will be set correctly and the error is visual in nature. We will work on a fix to this as soon as possible! Open a ticket if you are directly affected and would like to be notified by support when it is solved :)
*Update: We have found a workaround for this issue!
