Why is whi.min function designating a different row as its output when values show there to be a different one as the minimum value?

Question

Under hospital mortality rate of pneumonia (below), row 104 has a value of 9.7 and row 99 has a value of 10.5. When Running which.min, hospital name that is returned is row 99 and not row 104. Why is that?

R version and System:

-Windows 10
-R-3.6.1

Calling the function:

best("AK","pneumonia")

Using this function:

best <- function(state, outcome) {
     #read file function

  #Reads the csv file
  dataTable  <- read.csv("outcome.csv", header = TRUE)
  dataTable
  #Passes the state argument to the choice variable
  choice <- state
  #selects all rows which match the state that was selected
  stateOfChoice <- dataTable[dataTable$State == choice,]
  stateOfChoice

  #Makes sure that only three of outcomes found in the csv file are selected
  if(outcome != "heart failure" && outcome != "heart attack" && outcome != "pneumonia"){
    print("wrong condition, try again")
    main()
  }

  #using the selected rows from above, return the minimum value of rate from heart attack and then use this selected row to find the hospital name
  else if (outcome == "heart attack"){


    heart_attack <- stateOfChoice[which.min(stateOfChoice$Hospital.30.Day.Death..Mortality..Rates.from.Heart.Attack),]
    heart_attack
    hospital <- heart_attack$Hospital.Name
    hospital
    return(hospital)
  }

  #Similar as above, but instead with heart failure
  else if (outcome == "heart failure"){
    heart_failure <- stateOfChoice[which.min(stateOfChoice$Hospital.30.Day.Death..Mortality..Rates.from.Heart.Failure),]
    hospital <- heart_failure$Hospital.Name
    return(hospital)
  }

  #Similar as above, but instead with pneumonia
  else if (outcome == "pneumonia"){
    pneumonia <- stateOfChoice[which.min(stateOfChoice$Hospital.30.Day.Death..Mortality..Rates.from.Pneumonia),]
    pneumonia
    hospital <- pneumonia$Hospital.Name
    return(hospital)
  }

}
