Not sure if this is issue of the Title module which I have enabled, or just a bad configuration.
To reproduce:
1- Create a content type: My content and checked Enabled, with translation
2- Create a english node with title: My english node title. Save
3- Create a translation for that node to french with title: My french node title. Save
4- Now(after I saved the french node) if I go to edit the english node the title field is empty
It happens in the other way too. If I edit and save the english node and then I go to edit the french node the title field is empty
How can I trace this? It seems a bug to me, but not sure.
