Change MessageFilterExtension Display Name

I am able to create multiple MessageFilterExtension modules in my application. However, when viewed in the Settings > Messages > Unknown & Spam list, they all have the same name: the name of the application.

I tried setting the Product Name when adding the target and the Display Name after creating it, but they all still have the same name in the list.

How can I change the display name to differentiate multiple MessageFilterExtension targets? Or do I have to put them in three different apps to have three different display names?
