Cant load new Packages into SEPM - says already loaded, but not

Hello - Our SEPm was upgraded over the weekend and we are now at version 12.1.6168.6000.  I was notified that there is a new SEP version (12.1.6.MP2) that was released around the 6th of October.  I went to File Connect and dowloaded the files needed to load the packages into the SEPM.  When I tried to upload the new packages into the SEPM - it failed and said the packages already exist.  I do not see them listed.  are they named differently?

were the new packages not updated (as they are still dated 7/30/2015)
