The furigana looks right to me. Are you trying to say the position of the furigana is wrong? I mean... I guess in a perfect world they would be perfectly aligned so that each character sat an equal distance from each other, the way they would look in a book. But that seems like a pedantic level to hold this site to.
Jisho is capable of grouping furigana, like for the word 長い間 for example. The なが part is above 長 and あいだ is above 間.
Here however grouping is wrong - 長 is not な and 生 is not がい.
It should be 長=なが and 生=い.
@Erundil if people really care to have these aligned and want the creator to manually do each one, emailing is probably the better option, otherwise this forum will be nothing but furigana alignment threads.
I'm still of the opinion that as long as the kana are correct, it doesn't matter where exactly they are. The creator has a ton of important things on their to-do list that still need to be addressed at some point, and they do this all without compensation.
