Duplicate uncompleted tasks from previous week

This has been going on the last few weeks, and today I wanted to be certain I clicked "Copy uncompleted goals from previous week" ONCE.  It created a duplicate goal for every role that copied.  I can delete them from the Roles column about half-way down, then no longer can delete each one.  As a work-around, I then have to drag those I can't delete into a day in the calendar and delete from there (which removes from Roles).

This is happening in Safari 8 - whatsmybrowser.org/b/56DIBTL

Thank you.
