Online Course - Advanced Expressions: Part 2

Question

Hi, everyone.

I'm learning from "Online Course - Advanced Expressions: Part 2".I have a question about "Exercise: Looping Functions (Online Course | Learning at Appian)".
Exercise: Looping Functions(Online Course | Learning at Appian)

The answer of "Scenario 4" is 1333 (1332 + initial value 1), but adding all the values of "local!sensor" gives 1361.The last value of 29 in the third map seems to be ignored.
a!localVariables(
 
  local!sensor: 
  {
    a!map(data: {125,92,22,63,73,28,19}),
    a!map(data: {35,65,92,22,63,73,28}),
    a!map(data: {2,35,65,22,63,73,18,29}),
    a!map(data: {9,35,65,63,35,28,19})
  },
....

....
  reduce(fn!sum, 1, local!sensor.data)

)
Is the answer 1333 correct?Is this behavior by design?

Regards!

I see the same behaviour on my Appian 23.1. I changed the code a bit to highlight the problem.

a!localVariables(

  local!sensor: {
    a!map(data: {125,92,22,63,73,28,19}),
    a!map(data: {35, 65,92,22,63,73,28}),
    a!map(data: {2,  35,65,22,63,73,18,29}),
    a!map(data: {9,  35,65,63,35,28,19})
  },
  
  local!sum1: sum(1, local!sensor[1].data),
  local!sum2: sum(local!sum1, local!sensor[2].data),
  local!sum3: sum(local!sum2, local!sensor[3].data),
  local!sum4: sum(local!sum3, local!sensor[4].data),
  a!map(
    reduceResult: reduce(fn!sum, 1, local!sensor.data),
    manualResult: local!sum4,
    sumOnly: sum(1, local!sensor.data)
  )
)
