7.1 Xadmin File Upload Directory configuration change

I need some assistance with the file upload directory. My customer is using org id = 3 and on the xcenter server, I have created the following path: /fileuploads/org3. In my Xadmin settings, the value I have for the File Upload Directory is : /fileuploads/org${organizationId}/ . However, when I try to upload a file, I get :

If I change the file upload path within the xadmin settings to be: /fileuploads/org3/', then it can find it and I can upload a file, but shouldn't it be able to pull the org id correctly from the configuration? The org id I have in my xcenter.properties is 3 - is there somewhere else I need to set that value? Or should I just set the filuploads path explicitly to 3 to be able to move forward?
