Animation on iOS dose not work normal

When I used the same ani.json file on both chrome and iOS ,iOS behave abnormal.

We expect the animation contains all the words as we design: “みんなのコイン”
But when we run it on iOS, the first word dismiss, only showing “んなのコイン”,
please help for check:

the json is
lottie-json

maybe this has to do with what AE effects have been used to create the words (masks or certain strokes?). What did you use to create them?
