Audio Source Effect Preset Resets to NULL every time editor is restarted (4.27)

Development Programming & Scripting

I’ve got a SourceEffectPresetChain with a SourceEffectPreset as the only object in the chain. Each time I restart the editor, the preset connection is broken. I open the SourceEffectPresetChain and this is what I see. I’ve tried creating new chains and presets and it still happens every time. I’ve tried disabling and reenabling the synthesis and DSP plugin, as well

What could be causing this?

On editor restart, this appears in the log:

LogUObjectGlobals: Warning: Failed to find object ‘Object /Game/Audio/Effects/Waveform_Enveloper3.Waveform_Enveloper3’
LogAssetEditorSubsystem: Error: Opening Asset editor failed because of null asset

Attempting to open the Source Effect Preset ‘waveform_enveloper3’ gives this:
LogLinker: Warning: Unable to load Waveform_Enveloper3 with outer Package /Game/Audio/Effects/Waveform_Enveloper3 because its class does not exist
