Hooper, I really have no idea what could be wrong.
Anyway, I re-did the whole way you are shown templates that are exported / imported - you should be satisfied with this version.
They are now displayed in one big table, with [edit] links next to each template(!!!).
Also new, in the select box where you select templates to export / import, original temlpates are colored green, and modified templates are colored blue. How user friendly is that?
Just finishing it off and I'll put the new version up in a bit.
Now that I have the [edit] link, please test it and make sure it really links to the right template!
