We have a field that should only contain one of a list of specific data values. Due to some bad data practices this field was populated with a ton of bad data, incorrect values etc. I have cleaned up the data, but when I look at filters or flow steps referencing this field, in the multiple values chooser drop down some (but interestingly, not all) of the 'bad' values are still showing up as options. These values definitely don't exist in any person's record. Is there any way of clearing these incorrect values from the drop down, to prevent future data errors?
