Custom fields not available in the attributes in the Score Builder - SAP Marketing Cloud (2002)

Hello, everyone,

After I have created custom fields, enabled them for the Score Builder and the Maketing scenario and also published them successfully, I should be able to see and select them among other attributes in the Score Builder and use them for my rule sets. However, I can do this for one custom field. It takes quite a long time until it appears in the Score Builder. But I need more other custom fields that I can use as attributes in the Score Builder for different rule sets. After I create the first custom field and enable it for the Score Builder, I fail with the other fields. I have created and activated them and published them successfully, but they do not appear as attributes in the Score Builder. What could be the error? How can I do this without spending so much time, because it looks like only one custom field can appear in the Score Builder in one day, which is crazy. I am actually running out of time.

Thanks a lot in advance!
