Thanks!
It looks like you've messed up your back template, because it doesn't include what you want.
The 2 buttons for the vocabulary audio and sentence audio
The back template has no reference to any audio fields. You have
{{furigana:Reading}}
{{Sentence-English}}
{{Vocabulary-Kanji}}x5
{{Frequency}}
If you have fields on your note for vocabulary and sentence audio, you need to include them in your back template via field replacement.
and the vocabulary Furigana are missing. There is a duplicate vocab sentence (without Furigana
The Reading field in your note is a sentence and not the vocab word. (Hence why you have a sentence with furigana being displayed.) You need to replace {{furigana:Reading}} with {{furigana:the right field name}}
There is a huge gap between the vocabulary kanji & the english solution.
You have <br/><br/><br/><br/><br/> 5 new lines between the vocab and the example sentence on {{FrontSide}}. That's the huge gap.
If you want to have a massive gap on the front but fewer on the back, you can replace {{FrontSide}} with a modified version of the html that makes up the front.
