SPlat 2017.5 Bus Output Issue With Older Projects

When adding a new bus to an old project the output buttons on the bus and all tracks fail to work forcing a close/reopen of Sonar.
 
Also, the curser changes to the <||> symbol when moving away from the Console View Bus area. It does this as it passes over the vertical move bar toward the track strips. Once past the vertical bar it should revert back to normal but does not.
 
P.S. Most of the little issues I report seem to occur when opening older projects in SPlat. This is why I keep older Sonar versions installed. Even so, SPlat seems to affect the older Sonar versions in ways that cause new issues with them. For instance, while playing a project in X3 with 2 tracks soloed, one track's output level will stop working and revert to -0.0 for the duration of the play.
