Cannot set auto success range to an invalid value in the AIPerception component

When modifying the value of "Auto Success Range from Last Seen Location" to a value that is not it's default, you can not set it back to its default -1 one value.

This was reported and tested in 4.22.1 (CL-6063286). This was reproduced in 4.21.2 (CL-4753647) and Main 4.23 (CL-4251604)

1. Open the UE4 Editor and create a Blank Template project
2. Create a Character Blueprint and add a AIPerception component to it
3. Add an Array element to Sense Config and select AI Sight
4. Change the value of "Auto Success Range from Last Seen Location" to 0 and then back to -1

Results: "Auto Success Range" forces its value back to 0.

Expected: "Auto Success Range" accepts the value -1 because it's the default value..
