Returns wrong measure level

[Former user]

When I am trying to read the measurelevel of a .zsav file using the pyton module I got a wrong measure level for a specific case.

with savReaderWriter.SavHeaderReader(input_file, ioLocale='en_US.UTF-8') as headreader: return headreader.measureLevels

In the above case if the measure level is 'scale' in the file it returns 'ratio' every time.

To suspect this issue i went to the file header.py measureLevels(self) --> This function is defining a dictionary levels = {0: b"unknown", 1: b"nominal", 2: b"ordinal", 3: b"scale", 3: b"ratio", 4: b"flag", 5: b"typeless"} How both 'scale' and 'ratio' comes under the same key in the 'levels' dictionary
