setSlicerState method not working for parameter textbox in report

[Zed101]

Hi, While the setSlicerState is working for all the visuals in the report, it doesn't seem to update only the parameter textbox visually even though I can see the state change effects on other parts of report.

No matter what value I set using the setSlicerState method, it just remains as it is i.e. 1

Here's the filter I send to apply the new slicer state

The value '66' is not applied in textbox, value remains '1'

As for its visual descriptor: here it is

As you can see, the type is slicer, so should change the value of parameter textbox, but it doesn't.
