Why is Rinterp To causing jitters?

Hi. I have a simple cone that is pointing at my pawn and sometimes but not always I get this jittering effect. Is there any way to fix this. Also I am using 4.6.0 incase this problem has been fixed in the latest version.

Thanks,

After careful review of the problem I think that Rinterp To trys to change back and fourth between two directions and gets stuck in between. Not really sure if there is a fix for this as of yet.
