Ring Pro directly to transformer, frying transformers.

Hello Everyone! I just purchased the Ring Pro/Echo 5 combo deal off Amazon. I did a ton of research and saw that I needed at least 16 volts AC and at least 30 volt-amps from my transformer. I realized my old transformer was not sufficient so I purchased this unit. It matches the specs required. [https://www.amazon.com/gp/product/B07Q1GRHLH/ref=ppx\_yo\_dt\_b\_asin\_title\_o02\_s01?ie=UTF8&psc=1](https://www.amazon.com/gp/product/B07Q1GRHLH/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1) I followed these instructions which is straight forward. It doesn't mention using the extra resistor box that came with the kit at all when you are bypassing the inline chime.

At this point, I thought maybe my transformer was bad from the beginning. So I purchased another transformer. Same exact thing happened it works for a couple hours and then fries the transformer. Last reported voltage says good. Last reported signal strength says RSSI-34 So now I am like $40 in on new transformers I am thinking the doorbell itself is some how back feeding power into the transformer. There isn't anything else I can think of why it is burning out the transformers? Is there some setting on the ring pro that is back feeding into that transformer? Is there something additional I should have wired up that is not shown in those directions? I think there is something wrong with the ring doorbell itself. Thanks!
