1) not true both start and finish dates are considering during the scheduling calculations

 

2) What type of finish constraint are you using ?

Not having these problems with any version 17 or 18.

As Santosh says the core sceduling algorithms have not (sadly) changed in almost 20 years

I need a refresher course, but as far as I know, automatic scheduling (using a software) really hates constraints especially for a "Finish Date". 

Why should a planner need a software to calculate the Finish Date of a certain project or activity when it is already known to him/her? 

A software may able to calculate a backward pass and of course a forward pass (for thousands or even millions of activities), otherwise, it's useless.

Likewise, a human Planner may be able to do the same for fewer activities. 

The difference is: Humans are prone to mistakes!

Perhaps, just remember GIGO.

17.12.1 is not the latest version. But regardless the core scheduling system hasn't changed for almost ten years.
