Submix Effects don't reset after stopping and restarting PIE

Hi all,

We’ve been trying to create a dynamic effect using the new EQ and reverb applied to a submix. Their default state is dry (eq gain set to 0db and reverb gain set to 0) and the parameters are updated with a timeline, which starts and stops via in game events.

We’ve encountered the following problem: if PIE is stopped while the effect is applied, upon restarting PIE those effects will still be active (e.g. eq gain down and verb gain up), even though that’s not their default state.

Is this a known issue? Is there something wrong in our setup? Screenshot attached for reference.
