Issue with SLM report with expanded details

I am running the SLM report with expanded details under the software compliance section in ERP

I have computer groups set up.   Basically it is all the computers and software in each country

For the groups I set up a few days ago all of the calcs are processing cleanly. 

For the groups I set up just yesterday the report is coming out incorrectly.  In these cases installs = licenses borrowed exactly and there are 0 variances for each software title.  This is true even though I have not loaded any licenses for many of the line items that show license coverage for the installs (licenses borrowed).

Is there a process that has to run each night to perform the calcs?   I have run the calculate function in SLM / Administration but that does not resolve the issue.

Help
