Format of Import when RTF is in IFS folder


We have a main template we are trying to run on JDE. In the Main template there is an Import statement that points to an RTF in an IFS folder. When we run the UBE in JDE, the XML produces but there is no BIP output. The template runs fine if we don't have the import in there and remove the Call tags for the subtemplates. We also modified the cfg file by setting the xdk-secure-io-mode to false so that when JDE runs a BI Publisher RTF it will perform the Import / Call functionproperly.
The import statement in our main template has a format looks like this. Can anyone verify if this is what the path is supposed to look like?

<?import: file:///\\devboxE1\root\BIP-Font\CMSSIgnatures080819.rtf?>
