This is a way to reproduce the problem:
1) Device A: Create a new page and write something on it, like "This is a temporary note."
2) Sync with device B.
3) Go offline on both devices and write something more in both devices. For example:
on Device A: "This is a temporary note. It's on device A"
on Device B: "This is a temporary note. It's on device B"
4) Go online and sync both devices. You'll notice it's now written: "This is a temporary note. It's on device A. This is a temporary note. It's on device B".
Of course this is just a simple example, but in real contexts things tend to get messy, especially with long notes. It happens that the paragraphs are repeated one after the other and not just all text on device A first and all text on device B afterwards.
Of course ot seems by this example that I could pay more attention to synchronization, but again, in real life things get messy, mainly because of internet issues. So it happens that I forgot I had already modified a note and I edit it again.
I don't know what could be the best way to fix it, maybe by generating two different pages.
This bug could be happening in different ways, but this is the only clear path I found to reproduce it
