Thank-you for your thorough explanation Jean-Pierre, it is very much
appreciated. Sorry for the noise.

Best Regards,

Brian.

Eeschema does not re-annotate already annotated components, including
unit selection.<br>
If a component is not annotated, it is annotated, also including unit
selection in packages to optimize the number of packages.<br>
This is not a bug, but the normal behavior (and I must say: the
purpose) of an annotation.<br>
And many times, selection of the unit by hand is just wasting your time.<br=

Annotation does this selection better than you can make it, specially
in large hierarchical designs.<br>
<br>
If you want to choose yourself the unit selection,<br>
1- annotate first, and select unit after (needed only when you do not
agree with automatic annotation selection).<br>
=A0=A0 (IMO, selecting units in a package by hand before knowing if they
are in the same package is a non sense).<br>
or<br>
2- When creating a component, lock the parts (usually, this flag is set
only for components that have non identical units, i.e. non swappable
units)<br>
=A0=A0=A0 So annotate will use the initial unit selection.<br>
