Primavera P6 17.12.1 is NOT calculating correctly!

I have used P3, P5, and P6 for many years, but this latest version of Primavera P6 needs URGENT REVISING!
It is really troublesome, and I will AVOID IT as much as I can from now on!

1) Even though the Start Date considers constraints entered after the project has begun, the Finish Date value is NOT considering!  Furthermore, the Finish Date considers the original Start date (without constraint) plus lag (if any), and can be entered DIRECTLY.  In this case it will function more or less like a "Finish Milestone" - without being displayed as such!!

2) The Finish Date of Finish Milestones with many FF relationships is NOT selecting the latest one, but instead, it seems to use the "Finished" value in its Status. 

Any help here?

    17.12.1 is not the latest

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

    I need a refresher course,

    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.

    Not having these problems with any version 17 or 18.

    1) not true both start and

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

     

    2) What type of finish constraint are you using ?
