2020 model require latest version, if you installed before Fortin release the install guide you are probably running on 2019 version which have this exact issue on 2020 model. Get vehicle in and make sure you have 79.57 in EVOALL module.

what's the service number of the module?

That issue happens because of what Mathieu said.
