Bug - Email customizations overwritten

-- HikaShop version -- : 3.0.0
-- Joomla version -- : 3.6.5
-- PHP version -- : 5
-- Browser(s) name and version -- : Chrome

When customizing e-mail via System -> E-mails initially the changes are saved. However, when re-opening and saving the exact same e-mail, the changes are lost.

Seems to be a serious bug....

To reproduce:
- Open e-mail
- Type some additional text in comments of HTMl-version
- Save & Close
- Trash can appears for customizations, so we're good...
- Re-open the same e-mail
- Save & Close
- All modifications gone.... ;-(

Hi,

You should update your hikashop to 3.0.1 version. This bug was fixed with it.

Thanks
