Multiple custom fields of WYSIWYG using JCE Editor

-- HikaShop version -- : 2.3.2 Essential
-- Joomla version -- : 2.5.24
-- PHP version -- : 5.3.13
-- Browser(s) name and version -- : Any

Steps to reproduce:
1) Install and make default the JCE editor.

2) Create two custom fields type WYSIWYG for product.

3) Product edit page screenshot - d.pr/i/Pvtg
The editors are grayed out. You can still type on it like a plain textarea but no formatting and no editor functions work.

4) Custom field edit page screenshot - d.pr/i/OC3b
Weirdly shows editor-in-editor.

I have tried disabling other editor plugins and buttons but the problem still remains. The problem doesn't exist when using the default TinyMCE.

I know this is probably a JCE bug but is there a way to force load TinyMCE in Hikashop while the Joomla global config is set to JCE?

Thanks

Turns out there's already a setting for that under Hikashop -> Configuration -> Main -> Editor.

All is good now.
