hostname missing for emails for removed packages

When mentors.debian.net sends package removal emails, it has sitename in Subject, but it is missing in body.

Example mail:

Date: Sat, 12 Dec 2020 18:07:33 -0000
From: "mentors.debian.net" <support@mentors.debian.net>
To: mnalis-deb@voyager.hr
Subject: ironseed has been removed from UNRELEASED on mentors.debian.net

Hi,

Your package ironseed has been removed from UNRELEASED
on  for the following reason:

Your package was uploaded to the NEW queue

Thanks,

mentors.debian.net

I seem to have tracked it down to https://salsa.debian.org/mentors.debian.net-team/debexpo/-/blob/live/debexpo/packages/templates/email-upload-removed.html but I'm unsure about fix; maybe {{ args.settings.SITE_NAME }} should be {{ settings.SITE_NAME }} as in https://salsa.debian.org/mentors.debian.net-team/debexpo/-/blob/live/debexpo/base/templates/email-base.html ?
