The Difference node no longer updates after the first call. It appears to save the values passed into it on it's first call

Note Possible workaround: If a clear node is used on the difference node it will clear out the saved values in the difference node

Steps to Reproduce
  1. Download the attached project
  2. Open the project
  3. Play in Editor
  4. Notice that there are two sets of numbers printed out event though the TSets being prepared have been cleared

Expected: The first set of number would print out the difference between SetOne and SetTwo and the second print string call would print nothing
Result: The Difference node appears to save the first set of number provided to it and no longer updates those values
