Apple notes overlapping handwriting

I've done a long page of handwriting on the notes app on my iPad air, and when viewing it on my MacBook notes app, the handwriting were all overlapped (from another note). And in another case, the writings are duplicated like a double vision. But if I double click and open the note in a separate window, it's fine. On Ipad it looks fine.

Duplicated note

Overlapped from another note

Update: Actually this one particular long note is overlapped on ALL my other notes.
