Scheduled for:
The fix for this issue will be included in R1 2019, scheduled for the mid of January 2019. 

Bug can be reproduced in PivotGrid => Olap Support in demo application.
Under all main categories in the designer, there is a folder called "Sets" that has the exact same content.

It either is mistakingly placed under each "category" or should be something that sits on top of them in a more global fashion.

Bug can be observed in Pivot Grid => Olap Sorting example in  the most recent demo.

Sadly i do not know what this menu is called in english (and the demo cannot change language) so here is a screenshot

Set it to 'Equal' 'Lisa Cai'




If you hit ok and refresh, all values are gone.
Weirdly if you change it to not equal, you still get zero results

When a label filter is applied and there are repeating groups for columns and rows the GetUnderlyingData method does not return the correct items. 

InvalidOperationException regarding QuickStyle Freezable is thrown when the control is opened in new STA thread.

I've been investigating a memory leak in my application and I've noticed that there are a lot of TypeBuilders and RuntimeTypes hanging around, and this number increases over time. Investigation into this shows that they are being held onto by the ModuleBuilder instance in the static instance of the Telerik PivotClassFactory.

It seems that the option to turn of sums has no effect for hirachie columns.
No matter if this option is checked or not, they do not disappear.

It works on regular columns.

When overriden in a derived class the GetAllNames method receives an empty IEnumerable in the "parentGroupNames" parameter.

Available in LIB version 2016.2.606, it will be also available in the 2016 R2 SP1 release.

If we apply a label GroupFilter to a RowGroupDescription/ColumnGroupDescription (through the GroupFilter property or through the RadPivotFieldList) matching groups from both the rows and columns are filtered out. 

InvalidDataContractException is thrown when serializing the LocalDataSourceProvider with a DataContractSerializer and a calculation (TotalFormat) is applied.

When you apply an average aggregate function (for example via the RadPivotFieldList control) a VerificationException is thrown. The exception message is: "Operation could destabilize the runtime."

Available in LIB version 2015.2.914, it will be also available in the 2015 Q3.
