Reproduction steps:
1. Open the project
2. Select "Audio Source" gameobject
3. Check the "Audio High Pass Filter" component
4. Notice that "Cutoff Frequency" variable is not a slider

Expected result: "Cutoff Frequency" variable should be a slider since according to the documentation it should be a range(10.0 to 22000.0).
