Localized title rationale

Hi,

out of one specific example, I would like to understand how does the database picks up the default localized title which shows on a title page.

Daimajin gyakushû is displayed with the localized French title "Le retour de Majin":


But Firefox tab indicates "Le combat final de Majin (1966)":


At this stage, there are no attributes for both French titles:


And in the titleAkas file, they are ranked 6 and 10:


So I would like to understand how "Le retour de Majin" is picked up as default French title showing in the reference view.
(When it comes to the tab title, I guess this is the first one coming up...)

Thanks in advance for any feedback!
