How to mark task 100% complete on export in pds, excel and mpp

Hi,
I am using Aspose.Task ver. 22.9.0.0. I am facing a issue during making task 100%. In my scenario we have planned start, planned end, duration, actual start and actual end as well. No actual duration. When i export my project through aspose.tasks in excel, pdf, mpp format those tasks which have 100% completion turns to 99%. Even on some tasks their actual end get n/a.
Please note that I have set project Calculation mode to Manual. If i set it to none then our planned duration gets to 0. and when we set calculation mode to auto then above then 2000 task takes much time almost around 4 to 5 mins.
Please suggest the solution on it.

@rizkhanster,

could you please share the used sample code and template file (if any) so we can reproduce the issue?
