explainerdashboard 'what if' searchbox for index dropdown/selection isn't working

[AkshayRShiraguppi]

I am not able to type and search specific value in search box in 'whatif' and 'Individual prediction' tabs to choose an index.(When typed a specific number, it just shows wrong values in drop down and clears what i typed) (Random button seems to work fine)
I even don't see all index initially after clicking dropdown in the index search box in what if section. I have to type something in the box and then i see the values.
