Problem uploading file

I've created a shortlist in GS22 last version but when try to upload the list in game it seems the file doesn't exist, because doesn't recognize the .slf extesion. What can I do?

Thanks

I used Genie Scout to create a shortlist, but it saves in .slf.
But FM21 load only .fmf.
Now I can't use the shortlist I created.
What can I do to solve?

There is a workaround at the link. I have tried it and it works
