Hi, I am using a MoviePipelineSetting_BlueprintBase to add a custom render setting.
This works correctly with local rendering but when trying to render remotely using Deadline I have a problem with a Saved\MovieRenderPipeline\TempManifests\TempManifest{ID}.utxt. It seems like my custom setting get incorrectly written to the manifest and when loading render job it errors.

Log message:

Script Stack (1 frames) :
/Script/MovieRenderPipelineCore.MoviePipelineBlueprintLibrary.LoadManifestFileFromString

here is a look at my custom setting and antialiasing setting in the QueueManifest.utxt
You can see that autogenerated manifest of the custom settings seems wrong.
It has Data in Base64 in it and the properties are inside packageMetaData and not filled.
