Tag issue

I’m using the same tag name with the different slug for some tags, and the different name and different slug for some tags.

1. Example: different name and different slug
– JP
– name: Computer
– slug: computer
– EN
– name: Computer
– slug: computer-en

When you type the name, both of them come up, and hard to say which one is en which one is jp.

2. Example: different name and different slug
– JP
– name: パソコン
– slug: computer
– EN
– name: Computer
– slug: computer-en

If you save as パソコン, it will be saved with slug computer-en, and opposite for Computer.

And idea ?
Thanks in advance.
