Can you please go to Settings->About and let me know what version you are running? Version 2.4.5 is the latest Windows 10 version available on the Microsoft Store (version 2.4.6 is currently being approved). If you are running version 2.4.5, please try creating a new song and see if you encounter the same issues with link points. If not, I'll need a copy of the song you are testing with. Please long press the song on the songs tab, and tap Share->Export as .msf. Then email me the .msf file at mike@zubersoft.com. If it happens even with a new song, then I'll have to work on reproducing the issue. I may additional questions for you in that case to ensure I'm working with the same settings as you.
Thanks,
Mike
