What happened?

Description

I make edits (translations) to an entry with one admin account and save the entry. Then I log out and log into another admin account and load the exact same entry for the same site. Now I see old content (untranslated) again. A box with a yellow border is indicating that content was restored/merged in.

Steps to reproduce

1. Edit a translation and save
2. Log out, Log in with a different account
3. See old un translated content again. Sometimes the yellow box shows indicating that changes were merged in. Sometimes it doesn't show, but the entry shows an "edited" note.

Expected behavior

If someone saved an entry, I would expect all other accounts to load the same published content

Actual behavior

Old untranslated content loads. Sometimes the yellow box shows indicating that changes were merged in. Sometimes it doesn't show, but the entry shows an "edited" note.
The field that is replaced with old un-translated text shows a blue left border. Not a yellow one.

I can't seem to find a way to prevent this merging in. It seems Craft keeps a "user version" of specific fields. The entries in question have been imported programmatically.
Looking into the code it seems that a mergeCanonicalChanges() is doing this. Is there some documentation about this?
