Yes, this is a know issue.
We had to fix it by ourself by overrideing the file /apps/wcm/msm/components/touch-ui/livecopies/livecopies.jsp
There is some code missing in jsp. you can compare 6.5.15 and 6.5.16
it is something like below but make sure you do a text compare
Boolean isPartiallyCancelled = lrStatus.getAdvancedStatus().get(MSMNameConstants.PARAM_IS_TARGET_CANCELLED_CHILD);
if (isCancelled == null) {
isCancelled = Boolean.FALSE;
}
if (isPartiallyCancelled == null) {
isPartiallyCancelled = Boolean.FALSE;
}
