Why does Microsoft Edge automatically delete all my favourites without asking?

[Windows Central Question]

Hello, so I've been using Microsoft Edge since it came out on Windows 10, imported my favourites no problem. However every now and then I open Microsoft Edge to find that it has deleted all my favourites and I now have to re-import them. It's annoying because the favourites I'm importing are from over a year ago and they have changed, and this is like the 3rd or 4th time this has happened since it came out.

Has anyone experienced this or does anyone know why this is happening and how to fix it?

First, consider it is windows. Windows does a lot of strange things which means you always need to have a backup.
