This question is a good illustration of a common problem in the Listening gapfill.
But it's something that you don't need to worry about. The Clerical Markers are looking for correct answers.
As long as you write the right answer, you'll get the point:
✅ New town, Newtown, NewTown, NEWTOWN, NeWtOwn, NEW town, newtown
❌ Newton (wrong spelling)
Remember that there are many variations in the place names, so IELTS has to accept other versions of the correct answer (the same is true for the way you write dates and prices etc).
[I used to live in New Town - people write it in many different ways!]
