Folders and contacts didn't completely migrate over to eM Client

I was having horrible trouble with Live Mail so I decided to change over to eM Client. When I loaded eM Client it told me I could migrate all of my contacts and folders over. When I did it everything seemed OK. That is, until I discovered that the migration only went up to 2016. Any information in my folders after 2016 to the present didn’t migrate. Same with contacts. Any that were added while on Live Mail after 2016 didn’t come over. Any thoughts?
