While merging allure reports showing incorrect execution time

Hi
I am using Allure reports for generating automation execution reports
I have created a Jenkins job for the execution of the report and I am storing daily execution results in a particular folder. I am trying to merge these reports in order to get a consolidated monthly execution report using **allure generate \folderpath1\allure-results \folderpath\allure-results**
but after aggregating report, I am getting wrong execution time when I am opening a particular day report its showing in Minutes(for example 6M 23 secs) but after merging with command its showing(14d 00h) which is wrong

I'm submitting a bug report

What is the current behavior?
Showing incorrect execution time while merging report

Reproduce the report merge using the command and daily allure-results folders described in the issue, then compare the execution-time data in an individual report with the aggregated report. Trace how the merge handles those result files and verify that the consolidated report preserves each day's duration instead of showing 14 days.
