BUG: Grid header combofilter

I have combofilter in the header.

When i click on the combo and the dropdown appears if i remove the selected values or simply give up selecting anything and close the combo an empty chip appears.

This happens when the multiselection options is set to true and one of the rows is empty.
Also the cell configuration is:

type: 'string',
editorType: 'combobox',
options: optionsList,

where optionsList is (key,value) pair.

The header configuration is:

const headerFilter = {
      content: 'comboFilter' as fixedRowContent,
      filterConfig: {
        placeholder: '',
        virtual: true,
        multiselection: true,
      } as IComboFilterConfig,
    };

I apologize for the delay with the reply.
