Box Trace for objects not ignoring "Actors to ignore"

Hey, i have a problem it’s pretty well described in the title. i can’t seem to figure out what i’m doing wrong…
here’s the BP:

The End Trace that’s supposed to be ignored isn’t and it’s instead it keeps counting towards the score.
am i doing something wrong? is there a trick to it?
im running UE4 V: 4.5.1 due to financial issues, is it a bug in this version ?
or am i doing something wrong?
Thanks
