I could see that, but I have no clue and their copy protection don’t allow investigations. You should report this to SSL, they must have an unusual approach of their 32 bit gui.
This problem only occurs in 32 bit. In 64 bit their cocoa plugins don’t have the problem. You can run in 64 bit if you need to use their plugins.
I have pb with SSL Duende X-EQ in cubase 5.5.3 see :
Are you using the VST3 or VST2 version ?
With VST2 no probs but in cubase the preset name is always ‘default’, issue with VST3 (white GUI or Half part greenish when I reopen a project with a X-EQ). SSL doesn’t know if this is a cubase or a SSL pb.
