Hello

I do not reproduce.
Su what version of ProjeQtOr are you? Are you sure you haven't activated a filter on a project that contains no data? Do you have any errors in the solution logs? of the browser?

- v10.1.2
- I see a difference on console :
For first month=1
=> 1495ms | page='../report/yearlyPlanResource.php' | destination='detailReportDiv' | formName=reportForm' (server:1391ms, client:104ms)
[Violation] Forced reflow while executing JavaScript took 80ms

For first month=2
projeqtor.js?version=V10.1.2.0322:181 => 261ms | page='../report/yearlyPlanResource.php' | destination='detailReportDiv' | formName=reportForm' (server:239ms, client:22ms)

and indeed SQL Errors :

HINT: No operator matches the given name and argument types. You might need to add explicit type casts.
