May I refer you to #27 and #29 (I do not wish to get into a pointless circular argument).
From what I see you don't have Waves plugins, yet you are peddling this as the same issue with DMGAudio plugins (it may well be but who's code is at fault is to be decided, I have my own opinions as you know). It appears that none of these plugins are hooking in correctly into Cakes VST engine in X3D when it comes to the presets (assuming your issue is absolutely identical to the OPs?), and it also appears I still have two questions that remain unanswered, anyway over the the OP as it's his thread not yours or mine unless you have anything helpful to contribute (an answer to my questions would have been nice but I guess you are not going to supply them).
BTW I don't see any point in reconfirming an issue that has already been clearly explained by the OP and confirmed by Bapu (i.e. further testing is not required, not that anything I do should be required).
Thanks.
