Having replays remain in the "raw" folder indicates that an error has occurred during post-processing of the replay.
Please search your logs for any such error (should start with "Saving replay file:") and when you've found one, post the complete log to https://paste.replaymod.com/ and link to it here.
Alternatively, if the log is already gone, you should be able to produce the same error by copying the replay out of the "raw" folder and running it through the Replay Editor (Main Menu -> Replay Viewer -> Select Replay -> Edit).
