wrong FINISH DATE

I am preparing a recovery program using P6 and I am facing the issue of having a wrong FINISH DATE.

The activity (selected) has remaining duration of 2 days and its predecessor's Finish Date is 25 Sept. With this scenario, I believe the activity has to have a FINISH DATE of 2 days after the 25 Sept - means Sept. 27. But the calculated P6 Finish Date is 23 Oct which is 28 days difference. I have FS relationship. Not only this activity but so many in my program as well. 

You can see in the gantt chart how it behaves.

I tried different Duration type but same outcome.
Why? Can anyone help me? Is there any way to do this? 

Im using a Retained Logic. I think progress override is not a good option as it breaks the sequence of the work.

All calendars are set to 6 days. 

Anyone who wants to check the entire program, I can send. Comment your email.

Thank you planningplanet community.

Problem solved. Thanks to to our fellow Raymund de Laza quoting his reply below:

The issue was that there is a predecessor of the predescessor of the predecessor of the predecessor which is not started yet and is driving the activity. Try to trace all the predecessor of the said activity. SN1 and SN 2 are driven by NOT Started activity A2440. 

It was indeed the PREDECESSOR of the PREDECESSOR that drives the dates.

 

Thanks to all who shared their opinions. 

Try looking at calendars and work periods

I've encountered this problem before. Take a look at your calendar settings, eg. number of hours per day, etc. This will affect your duration especially if it is resource loaded.
