• KOReader version: 2023.06.01
• Device: Samsung Galaxy S20 FE 5G

Issue

Language metadata does not appear correctly on .pdf documents. After attempting to correct the files in the .sdr folder, the information still did not appear correctly. I also attempted downloading and creating metadata with Calibre, but it still did not display correctly in KOReader.

Steps to reproduce

Version 1

1. Upload pdf to your device to read KOReader.
2. Update the language fields in the metadata files in the .sdr folder.
3. Restart KOReader, open the pdf, click the top right menu, then click the 'Book information' button to check the metadata.

Version 2

1. Download pdf's metadata from Calibre.
2. Upload pdf to your device to read KOReader.
3. Open the pdf, click the top right menu, then click the 'Book information' button to check the metadata.

Version 2: Calibre metadata

Context

I'm trying to import upload KOReader Vocab Builder info to VocabSieve, but the importer does not detect the book since the metadata does not match my target language. More details can be found here: https://wiki.freelanguagetools.org/vocabsieve_reader_import

(Also, feel free to give me formatting tips, I don't use GitHub often)
