FIlename not working as expected

[bybpow]

Hi,

I have this rule for filename: "${seriesTitle}\${seriesTitle} - ${season}E${episode}"

but then the downloaded file name has extra info related to the dub:
"The Dark History of the Reincarnated Villainess - 01E01.ja.mp4"
"The Dark History of the Reincarnated Villainess - 01E01.ja-JP.en.ass"

what options do i have to change or use to modify or remove this: ".ja-JP.en"
