Eraser is acting as the stylus within applications on the 13HD and not as an eraser.
We are using version 0.12 of libwacom and 0.35.0 of input-wacom in RHEL 7.3 version of linux. We are using MATE, so we don't currently have access to the wacom control panel.
We need to figure out where the eraser changed to stylus. Please share the outputs of "xinput list | grep Wacom" from your system here
Closing this bug since there has been no response and it seems to work now. Please let know if the bug should be re-opened.
