Kibana version V6.4.2
Firfox latest version.
I setup a FileName options, and then setup a LotNumber options whose parent is the FileName.
while I change the FileName drop down list, and apply the changes, the LotNumber list never changes, and it shows a lot of list, but those LotNumber list are all not belong to the FileName which choose from the FileName option list.
I have ever use V6.3.0 and it seems it works fine, dont know if any mistakes I have made in the visualization.
