Capture: Values do not pass to Custom Properties via Batch Registration

Several CISPro custom properties have been linked from CISPro to Hub via Extended Properties and Inventory Group mappings.  These are used in a Batch Registration Recipe.  Most of the properties work, but two text properties are not passing their values from Capture to CISPro.  The same two properties can be successfully used with a Scan Container Task to pass the data from CISPro to Capture.  What could be causing this issue?
