Were you able to find a fix for this? I've been wracking my brain and searching everywhere for a solution to this same problem. Not sure if this is/was on yours as well, but mine is showing a disallowed passive loss in the Before 2018 box with the amount that was my loss in 2022; first column in 2022 shows the 2023 loss. It doesn't make sense to enter the same number into the 2023 box, and doing this then changes the amount in the Before 2018 one, so I'm not sure if that becomes an issue. Prior to this year there was never anything in the Before 2018 box.
Hoping you were able to get it resolved and pass along the how.
