September 18,2023 is a Monday, the 20th is Wednesday. Tuesday, 18th September: [Core Feature] Free Roam Mode Preview (Matt, Lukas & JD) Thursday, 20th September: [Route Preview] East Coast Main Line + Flying Scotsman (Matt, Jamie & Joseph)
All the other streams in the schedule are Tuesdays and Thursdays. The thing is that the TSW4 early access starts on Thursday 21st, so it makes sense that they moved those streams to the previous day of that week (Mon 18th and Wed 20th). They probably copy/pasted the format for each week to save time, but forgot to change the day of the week when they posted the info.
Thank you for this - typo on my end (guilty!), but yes as mentioned above this is intentional so we can preview everything while the pre-order window is still open
