Kerbal Space Program

Just downloaded KSP 1.12 and noticed that a few engines have sound FX issues:
*Switch the engine on via staging or PAW and their "burning" sound effects will play even if they're not actually running at all;
*Throttle up and the sound effects change as normal, but kill the throttle with X and the SFX keep playing at the throttle level it was at before pressing X;
*Shut down the engine via PAW and the shutdown sound effect plays but gets cut off after ~0.1 seconds(?), this stops the running sound FX too but reactivating the engine will restart the running SFX.

Engines affected: Mainsail, Dart, Mastodon, Terrier, Bobcat, Thud, Nerv, Cheetah, Reliant, Swivel, Poodle, Kodiak, Skipper.
