Same issue with "ビビル" where "ビビッタ" was said.

When generating the language syntax, no space is added between katakana and kanji, which leads to furigana and pitch colouring not displaying correctly.

When the katakana is after a kanji, it works as intended. As you can see here where the kanji is moved.

When adding this card to Anki, it gets displayed correctly. After adding the language syntax, it says "バレるバレ" again.
