Mechanical chime not working with video doorbell pro 2

Just installed a Video Doorbell Pro 2 and upgraded my doorbell transformer to a 16V30VAC transformer ([https://www.amazon.com/dp/B07GND8RMQ?psc=1&ref=ppx\_yo2ov\_dt\_b\_product\_details](https://www.amazon.com/dp/B07GND8RMQ?psc=1&ref=ppx_yo2ov_dt_b_product_details)). I am using the pro power kit which came with the device. My ring doorbell says its getting 16V and is power level 1 with no issues. However, when I press my bell, the mechanical chime just buzzes. I checked the voltage at the transformer and I'm getting 18-19 V. All the connections seem OK. Any ideas on where to go from here? Thanks! EDIT: Getting a current at the Chime without the button being pressed and a draw of 6V when the button is pressed. Is this a chime issue?
