Ring G2 Keypad - Cannot Set property

Following the 2.2.124 update I can now connect with the Ring Keypad G2 but I am getting an error when I try and set any delay times on the device settings page:

2021-01-30 13:04:15.341 errorjava.lang.NullPointerException: Cannot set property 'armHomeDelay' on null object (setArmHomeDelay)

My ring keypad is using S2 Access Control.
When I enter a code and press one of the three buttons, that info seems to be getting through (shows code and user) but again fails with the error:

dev:2772021-01-30 13:16:05.444 errorjava.lang.NullPointerException: Cannot get property 'exitDelay' on null object (parse)

I have rebooted my C7 (just in case) and am still getting the error.

I guess it is probably because I have done something wrong in the setup?
