Thanks for the bug report! The copy and paste commands for properties in the mixer are only affecting the non-snapshot of the property - which is to say, they are technically copying and pasting the value of the property, it’s just that they’re not doing it in the correct snapshot.
This issue is already in our bug tracker, as we discovered it during some recent QA testing, but I’ll add a note to the bug report saying that you’ve encountered it as well.
Unfortunately, there’s no simple workaround for this problem. You’re going to have to copy the value of the property across manually.
