Japanese subtitles disappear before finishing the sentence in many youtube videos

Bug

Example Like this one:

the subtitle suddenly dissapears before finishing the spoken sentence
However this Problem does not exist in all videos but on most videos where there is more than one people speaking (that might be the cause of the problem)

No solution but just wanna report I’m having this issue too, seems to be only on videos with multiple speakers but they should fix this.
