The default Capacity Scan action will periodically run but will not upload the result file if there is no HW change on the endpoint.
The 2nd action forces a new file upload and BFI import will process the new file. What I am not sure about is the sequence of actions needed to process the Cloud designation.
One option is to rerun the one time capacity scan action on all the cloud designated computers.
I will check with our development team. How ever if you would like a support explanation, I suggest to open a case with HCL BFI support.
