Trouble replacing clips with comps

There are a few clips in my timeline that are sped up (150%). I sent these clips to VFX, and when I go and replace the footage with the comps, most frames match with proper TC, however there are some that aren't matching. I can work around this by splicing those individual frames and returning the speed down to 100%, however I'd prefer not to do this. 

Furthermore, there is a scale in and I noticed that as the clip is animating, the frames do not match even though the velocity, position points, and scale are all matching. How do I fix this?

Thanks
