Which configuration setting is used to update the way the URL is generated from WebCenter Portal?

We had the Configuration of Portal and the Content Repository to generate URLs for linking as follows (NOTE THE 'i' after /path REPLACES 'Enterprise Libraries'):

http://<server name>:8888/webcenter/content/conn/WCC1/path/i///Aviation/Illustrations/C27/C27J_M344226_KML_0003.tif

During recent patching that URL no longer returns the linked documents. The configuration setting that set the 'i' to be used instead of 'Enterprise Libraries' has been overwritten. The new URL link is as follows:

http://<server name>:8888/webcenter/content/conn/WCC1/path/Enterprise%20Libraries///Aviation/Illustrations/C27/C27J_M344226_KML_0003.tif

We have thousands of documents that that are linked utilizing the 'i'. We need to re-establish the configuration setting that replaces the 'Enterprise Libraries' with 'i' but am unable to locate the proper setting.
