There was a general issue burning CDs with iTunes 12.7.2.x for Windows at anything over 2x speed.
iTunes 184.108.40.206 for Windows appears to burn CDs normally at full speed and with mixed formats.
It can be downloaded from https://www.apple.com/itunes/download/. Some regional sites may supply an older version.
When burning or printing use the right-click context menu on the playlist in the sidebar. File > Burn Playlist to Disc still seems to be unreliable and may attempt to burn the wrong list.
Other reports suggest that 220.127.116.11 doesn't handle CD Text correctly or is unable to burn a full 80 min CD. You might want to go back to 18.104.22.168 for now if either of those cause a problem for you. See the iTunes installers section of Troubleshooting issues with iTunes for Windows updates for download links, direct from Apple, and instructions on removing the current build before you reinstall. In this instance you don't need to restore an older version of the database.
