Filtering parameter by upper case value

Currently the quick sign loading duplicate device value any pointer to load only lower case value , tried in query level in where clause but it is not working , is there way quick sight has feature before load check has upper case and filtering this value ?

Create a calculated field using the formula toLower(columnname) then use this new column for parameter creation. This will eliminate duplicate values.

Thanks , if i apply the formula the lower case is working but “Show relevant” filter not showing the filter name !

Can you share a screenshot of what you’re seeing and what you’re expecting to see? Thanks!
