Is the liberty a dual cam bow? I just replaced my strings on my parker and had kind of the same problem. Would get a right tear(point left fletching right)instead. Uncommon for right hand release according to easton tuning guide. It didnt matter what i did. changed to weaker spine increased poundage move rest right and left worked on grip and form changed to a drop away and still couldnt get it to paper tune. Then i started looking at the cams. The timing was right on but the cam lean at full draw was quite a bit so seeings my bow is a dually i just twisted the split bus to offset lean and whamo perfect bullet holes. I'm sure this probably isnt the same problem but just a suggestion.
