Using servermanager.Fetch after some threshold settings has no data

It seems when trying to access the data:

src = GetActiveSource()
data = servermanager.Fetch(src)
data.GetPointData().GetNumberOfArrays()

That for some threshold filter settings there is no accessible data from servermanager.

For example, here's the wavelet source and I show in the Python shell window trying to access the data. This works as expected, I see that there is 1 array: wavelet_threshold_0

However, if I change the range and repeat, there is no data. It seems to only be for some data ranges on other data sets I am looking at. Though clearly it is rendering some data in the Render view: wavelet_threshold_1

Perhaps I am not accessing the VTK array data in the preferred manner? It seems to work as expected in 5.8.1.
