N4 Time Variant presets not working upon reload in Logic Pro

Sierra 10.12.6, Logic 10.4.1, Latest N4

Hi, I'm having a problem with any time variant presets I use with N4 where it works fine when I first load the plugin and setting but when I close the session and reopen it, and N4 instances with time variant settings are 'fixed' at one point of the LFO (as far as I can tell). The plugin is changing the audio but the LFO part is not sweeping up or down, is locked in one position. If I re load the preset it works as it should, but this has to be done to all the N4s I'm using with time variant settings. Same thing then happens if I save, close and reopen. All other N4 instances (eq, comp, reverb etc) work as they should. Any ideas?

Thanks!

Same thing happens if I restart core audio within logic while a project is open.
