TAdvGridDropDown shows items that are outside the filter

TAdvGridDropDown ver
Click button for dropdown
In the search box type any filter
Click any item to select it
Open again the dropdown
The search box still has the filter, but items are not filtered.
If you navigate through the items the text box shows the next item that is filterd and skips the ones outside the filter.
It's somehow correct, but it's weird and confuses the user.
Is there a function to clear the filter once an item is selected and if the dropdown is open again the filter is cleared?
I just realized that even if you don't type in the search box, the filter persist...

Although I'm not sure how you use the search box to filter, you can clear the search edit control via:

AdvGridDropDown.Grid.SearchPanel.EditControl.Text := '';
