Translation Button Issue

I have 2 categories:

1. Used Books
2. 二手書籍 - Chinese for used category

Now I click the translation button:

[attachment=0:29r45y96]<!-- ia0 -->translation.png<!-- ia0 -->[/attachment:29r45y96]

So select:
1. Chinese
2. Select the "Chinese Category": 二手書籍
3. Select "Keep secondary category" to "no"

However, the Chinese version always appears in "Used Books" not "二手書籍".

If I use the copy button - it doesn't have this problem.

Why can't I change categories?

I have removed this limitation after other users request,

but if you select no subcats then the existing are maintained, right?

i ll put some check to detect distinguish
-- not changing subcats
-- from not selecting any subcats

I haven't tried with subcats:

+ Used Books
+ 二手書籍

The translation button is a convenience to save some time.

For now, use the copy Task ...and then edit your items to change language etc ...

i ll be making improvement to the translation button
