Grid's items are not correctly calculated when a group is expanded and groupPaging is set to "true".
The number of the displayed items is incorrectly calculated
The number of the displayed items should be calculated based on the number of the rows inside the opened groups
Whenever the foreign key column of the grid is configured for multi checkbox filtering and is nullable, the value of the "null" option is sent to the server as "NaN".

1. Set ForeignKey column
2. Make the column nullable
3. Set the filterable.multi option to true
4. filter by the null value
