front end editor corrupts translation

When I’m working on the translation of the main page through the bakery front editor using the English/Dutch language dropdown in the bluetopbar the full English translation is lost and is set back to the main (dutch) language.

Using the backend editor and the qtranslate-x plugin switching with the language tabs seems to work normally, but going to front editor is when it all goes wrong.

This is very frustrating losing work because of this issue..
anybody any ideas what is going wrong.
(have the newest versions of wordpress and of the bakery and qtranslateX plugins)
