## Is your feature request related to a problem?

When trying to create a filter for a query, value autocompletes are case sensitive. This throws up weird behaviors. 

E.g, with the country name filter entering 'f' as the first letter autocompletes to 'Africa' (and, for some reason, the Isle of Man) and 'France is not listed as an option. Entering 'F' autocompletes to France. 

## Describe the solution you'd like

Not case sensitive results, or else better filtering. Africa shouldn't come up if I only enter 'f'. 

## Describe alternatives you've considered



## Additional context
