Hello,
Thank you very much for the report and I am very sorry about the experience!
I tried to replicate this issue (with AC24 4018 INT) using a simple composite wall with 2 skins. Even though I created the schedule view with "Core Only" active in floor plan, the saved schedule view still shows all wall skins in 2D Plan Preview column.
Could you share some screenshots of which elements are included in the saved schedule view?
Thank you very much!
Best regards,
Minh
