I have a similar problem with the product short description / excerpt. It shows raw html text and changes to that field are not saved.

A workaround solution was to disable the visual editor globaly in my profile. But because I need the visual editor for other fields, I disabled tinymce for the excerpt editor:

woocommerce\includes\admin\post-types\meta-boxes\class-wc-meta-box-product-short-description.php

replace

'tinymce' 	=> array(
				'theme_advanced_buttons1' => 'bold,italic,strikethrough,separator,bullist,numlist,separator,blockquote,separator,justifyleft,justifycenter,justifyright,separator,link,unlink,separator,undo,redo,separator',
				'theme_advanced_buttons2' => '',
			)

with
'tinymce' => false,

thank you cj, I tried exactly what you wrote but when I do this it disables totally the short description, there is only the title but no box at all anymore. I think I will wait for mqtranslate to fix this issue before I translate my site ??
