Bootstrap Tabs doesn't work when language is changed to 2byte character languages

[Susumu]

Hi, I'm using v2.20.2.

I changed language to Japanese, and I edited translation file(po).

It almost works fine.

But a few pages don't work enough.

The pages are for adding contact, and adding campaign.

These pages use bootstrap tabs by using django-crispy-forms.

When I use other language (maybe 2byte character languages), the tabs can't be changed.

I'm very happy if you tell me how to solve this situation.

Thanks in advance

Regards

Susumu
