It's not supported to export JSON from 4.3 and import it into 4.1. That 4.1 is able to load the JSON data is a coincidence and there may be problems, such as the feet. If you must do that, you need to choose version 4.1 when exporting JSON -- but be warned doing that may lose data:

    Nate 视频当中忘记选择为4.1版本了，实际上选择4.1版本一样会出现上述问题

      I did the steps shown, exporting spineboy but with 4.1 selected, imported that into 4.1: the feet were correct and frame 7 showed 7.

      I don't know why you would see it happen differently, so I'm not sure what we can do. We don't go back to older versions and fix bugs. We are happy if we can fix something in 4.3 that would help when bringing data back to 4.1, but if the bug is in 4.1 then there's nothing we can do.

        正是因为帧太近了，所以鼠标点击看不出来，应该用快捷键才能发现这个问题，当4.3导出json再进入4.1的时候，会出现小数帧

            yugutou Thanks for posting the video! I was able to reproduce the decimal point frame problem, but when I exported Spineboy from 4.1 and imported it into 4.1, I got the same results. So I think this is not a bug in the 4.3 export function, but in the 4.1 import function. Unfortunately, as Nate answered, we cannot fix this problem because we cannot fix bugs in older versions.

            I wasn't sure how to reproduce issue 2 in your first post, have you found a way to reproduce this?
