Help with GeneralisedSobolSensitivity()

[Landflier]

I created a script which should run GeneralisedSobolSensitivity() on a third party model. I created a wrapper class BlackboxModelUQpy for that, and used RunModel( model=BlackboxModelQUpy() ). However, when I pass the number of samples n_samples=2 to the GeneralisedSobolSensitivity().run method, it runs the model 22 times (2*11) for some reason.

I cannot understand why the number of runs is so many. I can post my script somewhere, for reference ;)

Sincerely,
Vasil
