yes, now the waveset parameters are under <object>.visual.waveset rather than just <object>.waveset

this was changed for 1.5.0, so if this just started happening after a plugin upgrade, the reason is that you're looking at a default waveset and your settings aren't being applied.

Almost everything of the age could get repaired. Only some things had to be changed in another way. But... Maybe it opens new possibilities. *think positive*
