Favorites links keep disappearing IE 11

I know everybody is switching to Edge, I'm not real crazy about it. My problem is with IE 11. When I add a link in "add to favorites" I can see it. Once I close my desktop PC down for the night, the next time I open it those links are gone. I have checked the favorites folder in C:/users/username/favorites, all or at least most of them are gone. The folders I created are empty???? One or 2 might still be there, usually not. Any fix for this??? No point in saving a link if it's not going to be accessible the next time I need it.

try this one:

Click Start.
Click Computer.
Type %userprofile% into the Address bar.
Press Enter on your keyboard.
Right click the Favorites folder.
Click Properties.
Click Previous Versions.
Wait for the list of previous versions to load.
Select a version that was before you lost the files/folders.
Click Restore.

Won't that make my Internet Explorer even more vulnerable, the previous one would be IE 10??? Not even sure if that works with windows 10??

I just gave it a try and it says there are no previous version available??

It happened again this morning and there weren't any updates performed on my PC at all yesterday. I was busy and it never got turned on. This morning I went to access one of my "Favorites" links and they are gone again. Is there a patch or fix for IE 11??, or is this their way of saying "use Edge"?
