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?
