That's expected behavior. MKVs are not widely supported by all clients to begin with. MP4 are, so there's way less of a chance that MP4 containers will cause a remux.
What Jellyfin is doing is remuxing your MKV container to MP4 so that the client can play it.
This is not a bug. The client just can't handle MKV containers most likely.
In order to remux, Jellyfin needs to store the final result in the transcode directory where it's then sent to the client for playback.
