Thanks for the file. When I imported the json file it was the profile of your project.
- imported the json file and opened the profile in SP.
- In SP in the Bowl setting window I set segments to 16, tornado bowl.
- in SP went to Story Board. Entered 4 in the Tornado Band per row.
- In Story Board Tornado Repeating Pattern initially Segment 1 - 3 was shown. When I entered the 4 in the Band box a fourth segment box appeared.
- Wood selection depends on the palette you are using. S1 cherry, S2 yellowheart, S3 Padauk, S4 maple.
- Selected Summary. The table seems fine.
- saved project plan from bowl setting
- share / export and attached the json file
Not sure what caused your error. I suspect the database got confused.
