Ubuntu MATE 20.04 for arm64 checksum not matching

Downloaded a few times on different computers and the check sum is always the same but never matches what is on the download page. Used what is recommended by the site MD5_and_SHA_Checksum_Utility as well as get-file hash in powershell get the same as below every time.

233C268963637C94A3527B90FCE3CF74EEAAF03E9D3A5623457B4B2412778DAA
should be
ubuntu-mate-20.04-beta1-desktop-arm64+raspi.img.xz|

SHA256SUM 82019e65bf836c10a7f4f787757e6f317ea8b9508f15ee23d25a85ef5107e9bc|
