# Facebook reports errors (syntax not supported)

 * After creating custom audiences in Pixel Caffeine, I checked them in Facebook
   Audiences. When I try to edit a custom audience there I get this error message:
   This rule was created through API or third party applications. It contains syntax
   that we currently don’t support in our interface.
    Please advice. I’m not even
   sure the custom audiences created are working. Also, I’d like to expand the retention
   but I don’t see them anymore in Pixel Caffeine and I can’t edit them in Facebook
   Audiences. What should I do?

 * Hi,
 * the custom audiences created from the Pixel Caffeine admin can be edited only
   from the Pixel Caffeine admin, where you can also edit the “Retention” field 
   if you need.
 * They may including some complex rules that the Facebook interface can’t reproduce,
   but they works properly anyway.
 * If you want to check if the custom audience is working, you can check for the
   size .
