LTM to XML,script reading LTM Virtual server created by iApp

I created a Virtual server using an iapp, and created other ones not using the iapp method. When I run the LTM to XML script, or the BIG-IP visualizer script, it tells me that the virtual server does not exist. But If i run the scrips ref a virtual server that was not created by an iApp, the scripts run with no issues. I'm looking for any assistance or guidance on how to troubleshoot this, as I see great value in using these scripts for documentation purposes. I'm running 11.6.0 Build 1.0.403.
