Chime Classic - ring tone and volume do not actually set

I have my Ring camera set up, and notifications are working. So then I installed our Chime device (original version, not Pro); it is installed, and ran its updates and such. Then I went in with the app to change the tone and volume... I set them as desired (using the Train Whistle tone), and when I press "Test new tone", it plays the one that I selected... but when we actually get an event, it plays its default tone - at FULL volume!! Is there some way to actually get the Chime to use the tone/volume that I've programmed into it?? I also tried unplugging/replugging the Chime after setting, but it made no difference...
