We found a missing Sill component part in the framing system ID:4139, "B4 : CT451 Storefront (2 x 4-1/2) : 1 inch Glass : Thermal".
You can add the CG451-4 Sill member to the Stock Length Material tab of that framing system from the Framing Systems link in the menu tree. See the screenshot below for details.
The updated 2022 r4 has this correction along with the CG451 corrections that were made earlier.
