MZ Values not sorted after conversion and peak picking

OS: Windows 10 64 bit
Raw file parser version: ThermoRawFileParserGUI-1.6.0

When converting an Orbitrap Exactive raw data file, negative acquisiton mode not all m/z values are sorted. I'm not sure if it's actually a bug and m/z values are not guaranteed to be sorted, but every other value seems to be sorted ascendingly.

See here:

This is in scan number 1/index = 0.

Is it expected/unexpected behaviour?
