As per #142
This behaviour of taking the first matching alternative title instead of the main one really confused me before digging deeper.

With

     postProcessing:
        seriesTitle: true
        seriesTitleLanguage: "en"
        fallbackToAltTitle: false

I expected it to use the en series title only but instead it ignores it and sets to the first en altTitle if it exists - even with fallbackToAltTitle: false

#142 (comment)

Also Komf ignores main title completely and only takes altTitles since main title often tagged wrong.

I think if the metadata source is wrong then let it be wrong 😛

Anyway requesting this behaviour be reverted or at least configurable to use main titles again thanks.
