Issue with durations and roman numeral analysis tool

[Joseph Srednicki]

Hello:

I am having difficulty with durations and the roman numeral analysis tool roman_numeral_analysis_tool.ily, which I downloaded from GitHub - lyp-packages/roman-numerals: LilyPond typesetter for Roman numeral harmonic analysis

See the tiny example below.

In this example, I have used beat durations in the analysis section of the source code. 

Based on the input, I expect the vi 6 4 to appear beneath the final sixteenth note of the second beat of the measure. However, the vi 6 4 appears under the first note of the third beat in the measure.

Can anyone please help detect the error that I am making?

Thanks for your help.
