Space Designer Presets Missing

Hi all,

I have been working on Logic Pro X and realised that all Space Designer presets are suddenly missing. I have the SDIR files in the Audio - Impulse Response folder, and can load them manually on Space Designer by selecting 'Load IR'. However, when trying to search through presets using the top left dropdown they are nowhere to be seen. All was working fine during my last session but the presets have suddenly disappeared today for some reason.

Any help on this would be greatly appreciated!

Thanks
