Sorry it took so long to get back to you. I was checking with a colleague.
Page 2, We agree on how you transcribed this using the square for the omission. Include a TN about the other numbers in a square.
Page 3, We would use transcriber defined print symbols for the "bullet" and "bullet within a circle". It would use less cells. Include a TN.
Page 4, Looks good as you have it using transcriber defined symbols. You may need to change them to third and fourth if you use first and second on page 3.
I hope I answered all your questions.
