A little confused on Ram build

[jamminj]

Looking to eventually get a 2500 built. Little confused as to why the Ram website says "build 2020 Ram 2500" then when you click on it, there is an option to build a 2021?
Are they still building 2020 Ram 2500's for special orders? I also noticed option packages differences between 2020 and 2021. It's all a little confusing.
Can anyone shed some light on this for me? Thanks

You cannot order a 2020.

Option packages changed a little 20-21 and the chip shortage issue has also caused the trims below Limited/Longhorn to have altered packages due to the drop of Blind Spot monitoring and crosspath detection.

You can "build" a 2020 with your desired options to search for inventory but cannot order one.
