SEPM: Error when attempting to assign client install package

Hello,

I'm running SEPM 12.1 and trying to assign SEP version 12.1.3001.165 to a client folder:

I'm in the "Clients" section and navigating to a specific folder. I then click on the "Install Packages" tab and right click in the window and select "Add". I get all the options for adding it but once I click OK I get the error:

Console Error

The replicated software pachage can not be find in the cache. [0xf0000000]

Does anyone have any idea on how to sovle this? My first thought was to delete the install package and reimport it but SEPM won't let me do that because its the "newest version."

Thank you.
