Issue with CDN link in canonical url

Hello Team,

If you check the source code of below URL

https://www.itzgeek.com/amp/how-tos/linux/ubuntu-how-tos/how-to-install-ubuntu-18-04-lts-bionic-beaver-on-uefi-and-legacy-bios-system.html

you will see the

<link rel=”canonical” href=”https://www.itzgeek.com/how-tos/linux/ubuntu-how-tos/how-to-install-ubuntu-18-04-lts-bionic-beaver-on-uefi-and-legacy-bios-system.html&#8221;https://cdn.itzgeek.com/>
<title>How to Install Ubuntu 18.04 LTS (Bionic Beaver) on UEFI and Legacy BIOS System</title>

Don’t know why https://cdn.itzgeek.com/ is coming in the url.

I want your help to remove the CDN URL from the canonical link. It happens only to a few AMP pages.

The page I need help with: [log in to see the link]
