MineMeld mining IBM X-Force TAXII/STIX2 source feed

[ACMENEWS]

I have MineMeld setup to poll my IBM X-Force TAXII feed, however no indicators are being retrieved.  At this point, I simply want indicators from a specific X-Force collection to feed into a mirror copy within MineMeld.  The collection has indicators.  I have added a large number of indicators just a few minutes ago.  Re-polling the feed results in no new indicators within MineMeld.  

I have had this working before in a prior version of MineMeld at a site that I no longer have access to, thus I cannot reference that configuration.

This should be simple.  What am I doing wrong?     Thank you.
