I have a few reports in which I have a multivalue parameter that renders a ListView control.  However, when the user clicks on "Select All", only the 1st value is sent to the server.

Also, if some of the values have default values when defining the Report parameter and one of them is the 1st value, then ALL values are pre-selected when the Report renders. However, when the user clicks "Preview", again only the 1st value is sent to the server.

The above happens when I reference Kendo ( kendo.all.js) 2020.2.513 in the project. With Kendo 2020.1.114 the viewer works as expected.
