OrCAD Capture annotation issues for a heterogenous part in a hierarchical design

SF202503203610

I have a hierarchical block that is used 64 times.  Within that block I have a quad opamp that was pulled from the included OrCAD library.  The reference designators are U?A, U?B, U?C, U?D.  When I annotate this block, (Update Selection is selected). I do not get the annotation that I desire.  I want

Instance 1:  U1A, U1B, U1C, U1D

Instance 2:  U2A, U2B, U2C, U2D

....

Instance 64:  U64A, U64B, U64C, U64D

but what I am getting is 

Instance 1: U1A, U2B, U2A, U2C

Instance 2: U1B, U3A, U2D, U3B

etc

I have tried using Update Occurrence, Update Instances:, Annotate as per PM Ordering, Annotate as per page ordering in the title blocks, Preserver Designator, and Auto-package Heterogeneous Part Using First Match, and they seem to have no effect.  I have tried "Advanced Annotation"  but it just opens and locks up.  The only button that works is the X to close the window. I even changed the reference designator for this part to UQ?A, UQ?B, UQ?C, UQ?D so that there would be no conflicts with any other "U" parts, and the output was pretty much the same.  I have OrCAD X Capture 23.1, but I have noticed this behavior in previous versions of OrCAD.  

I'm beginning to think the only solution to this is to annotate it, then go in and manually change all 256 reference designators (4x64).

    The hierarchical block which you have placed 64 times is it referencing to internal or external schematic design ?

    Can you share Tools > Annotate snapshot with us-

    Also, please refer Cadence Document which explains how to use advanced annotation in a hierarchical design

    The hierarchical block references another schematic page in the same .dsn file that also contains the hierarchical block.  

    I am unable to upload the Tools -> Annotate snapshot.    When I upload the image from my computer the forum gives and error, and when I try to use an image hosting site, it flags my post as SPAM.
