Build Pipeline Plugin - Jenkins - Showing only LAST Build Number of child job and only once (called from Post build action)

Question

Jenkins: 2.89.4.x (or rolling)

Build Pipeline Plugin version: 1.5.8

High level info:

I have JobA (parent), which calls JobB (twice in Build Step - either sequential or parallel) and calls the same JobB (twice in Post-Build Action). JobB is simple. It has just one parameter 'what' and each time Job A calls JobB, I'm passing a different parameter 'what' value.

A ->B -> (->B,->B in parallel)
  ->B

• Therefore, there are 4 times call to JobB per one pipeline run of JobA. i.e.

NOTE: This value of 'what' parameter printed in JobB's console output and using Set Build Description(plugin) for all 4 calls - WORKS!

ISSUES 2 of them:

1. Build Pipeline View is showing the LAST BUILD# of JobB in the GUI/Visual page.

2. Build-Step calls JobB twice and it's showing up in Build Pipeline View two times (as expected) but Post-Build Step which calls JobB twice, is NOT showing in the GUI page.

Job Config / Run Info:

JobB's configuration is:
