reporting

I'm building a report which is basically a big set of pie charts (13 of them) grouped by user.

Each pie chart uses a diferent query (actually, same query, different table). I laid them down, and everything was fine until pie number 11. Pie number eleven crashed PRD with the error:

org.pentaho.reporting.engine.classic.core.InvalidReportStateException: Assert: Shift is not as expected: realY=252100000 != expectation=251700000; Shift=63200000; AdditionalShift=-400000; RealShift=62800000

I checked the query on the underlying SQL Server and it is ok.

Anyone can explain what is happening, or give me a hint about what is failing?

Full stacktrace:
