I have a really strange issue I can't seem to get around. Data goes missing from a report I deploy to the report server, when it works just fine in preview on my local machine (as well as other employee's local machines). When I run the report in Preview mode in SSRS, I get the following display, which is correct:

Notice there are four rows (due to correct grouping) and a boolean value (False) displayed on each row.

When I deploy the report to the server (SQL Server 2008 R2), grouping for some reason combines the four rows into two, and the boolean values disappear:

I have deleted the report from the server, cleared my local machine cache, emptied my /bin/ folder and restored from our repository, and tried previewing the report on other colleague's machines. It works *fine* on everyone's local machines, but the report server seems to be missing something.

Any ideas?
