Fabfilter plugins causing start delay

[Morgan]

Good morning, I’m having a delay problem when using Fabfilter plugins. For example if I place Fabfilter Timeless and Saturn into a subgroup when I hit the play button I get a 2 second delay before the project starts to play. Remove the plugins and everything runs ok. These are not the native Fabfilter plugins but the equivalent AUv3 versions. The issue doesn’t effect the project in any other way and I can live with the delay but just wondering if there is a work around as I like using the latest fabfilter pluggins. I lost the original Fabfilter native plugins when I upgraded to Auria Pro and ditched the basic version of Auria pro. Any help would be appreciated. Thanks Trevor.
