Bug ms project 2019: fixed work task changes after change in unit percentage

Question

A task with Type: Fixed work and 8 hours has changed the work after changing the unit percentage to 10% into 0.8 hours. I think this is a bug because definitions below. Am I right? ms project professional 2019

Define: Fixed Duration, Fixed Units, Fixed Work

Fixed Duration: The task calendar ‘Duration’ will not change when you change the ‘Work’ or add resources.

Fixed Units: The resource percentage of work will not change when you change the task ‘Duration’ or ‘Work’ hours.
Fixed Work: The ‘Work’ hours will not change when you change the ‘Duration’ or percentage of resource work.

Jan Willem Tromp1,

The task type definitions cited are not totally hard and fast. As a starting point they hold but various scenarios during editing can cause changes.

In your simple example, the work has NOT changed, it is still 8 hours. What has changed is the duration. When the assignment level is changed to 10%, you will see an option to change the duration (default) or keep the duration the same and change the work content.

It's not a bug, it's the way Project works.
