I used export to .msf file. Both export and import was done on Windows 11, latest version of MS - 3.8.25 . I've checked that original files have IDs, export them into .msf file, cleared the library and restore original settings but still no Sond ID after import of .msf file. I've just sent you .msf file via email so you can check it. There are 3 songs in there, IDs should be 185, 77 and 305.
