Hmmm, I've realized using an older version without the newer menu the replays are fine if you load them(not quick load them)ingame. I have the newer menu and it seems that there is only one load button(which is view replay), and it seems that this load button is simply the old quick load button.
Just thought to get that out there, so for now you might need to use an older version to get the replay to speed up or slow down, also, you can tell if it's also working if the multiplier is black or gray, if it's gray it isn't workin (Like your image) and if it's black then it should work.
