Kicks over time - Version 4.5

For my Big Band drum parts I use Kicks over Time. Since version 4.5 I'm unable to move triplets to voice 3. It works with all other rhythms with the exception of Triplets. In the previous version all rhythmic values would work using this procedure:

1) enter the desired rhythm in voice 1 (eg, using snare)
2) exchange voice 1-3
3) toggle rhythmic slash notation
4) fill with slashes

Thank you.
