Import/Export woes/misunderstanding

[nightpanda2810]

Before I post a feature request for more robust import options, I'd like to make sure I'm doing import/exports correctly.

I have a base realm, called Template. It is system agnostic. Every single default tag/category/etc is disabled, and I use all my own. It also has various pre-included things that every campaign I run will have, such as history, towns, etc.

Before now, I only had one campaign based on this template. I'm now working on a second in the same world, but in a different starting location within that world. All my future games will be in this world in some form.

Now, when I find something missing in the new realm I'm working on, I'd like to add it to the template (whether its a category, NPC, etc.), then export and import into the new realm and the old.

Here's my import/export procedure.

Find I need a new category. Lets say the name is Business.
Exit and sync current realm.
Load template realm.
Create new category called Business.
Leave everything else alone.
Goto Manage Exports.
Since its just a category, I use Structure Only.
Uncheck the box "Preserve original authorship..." as its all my own built data.
I load up the realm I want to import to (making sure its synced first).
Goto Import.
Select my structure-only import file.
Expand advanced options.
Choose both of the "Overwrite the conflicting..." options.
Uncheck database backup, as I have the realm synced.
Choose Import.
Upon completion, I get the following.

Note: The same thing happens if I choose to ignore the conflicting data.

    *snip*
    Category 'Region' renamed to 'Region01' due to duplicate name
    Category 'City/Town' renamed to 'City/Town01' due to duplicate name
    Category 'Regional Adventure' renamed to 'Regional Adventure01' due to duplicate name
    Category 'Locations' renamed to 'Locations01' due to duplicate name
    Category 'History Etc.' renamed to 'History Etc.01' due to duplicate name
    Category 'Quest' renamed to 'Quest01' due to duplicate name
    Category 'Quest List' renamed to 'Quest List01' due to duplicate name

Every single category gets a duplicate, that I then need to go in and delete them. One at a time, with "are you sure?" prompts. And scrolling down past all the inactives, since a change anywhere. expands the collapsed section.
How do I stop this?

What I want to happen is the category gets updated with changes, or is ignored if there are no changes.

Every existing category has been used in the realm in some fashion.
