Checklist Filter not Working When Capital Letters Used in the Label

[asavage]

When I have some items with labels that have a capital letter, the filter does not appear to work. It shows the labels correctly. When I select 1 or more that have a capital letter, no values appear. It does not seem to matter where the capital letter(s) are in the label

This is a bug in the Selectors file. I can provide a fix if you are still interested, but this extension seems to have gone long time unmaintained. Hence I won't be able to publish it with original publisher.
