I recall the Perfect Space convolution reverb having a big latency hit, and I was running older hardware at the time, so I never used it.  But I have noticed now that the REmatrix Solo convolution reverb seems to run very well for me, without any noticeable latency.
 
Anyway, thanks for all of the explanations.  I wasn't calling out a bug, just wanted to understand how it worked.
 
I'll just keep LP EQ in non-linear mode, or use Quadcurve EQ ... unless I am mixing ...

This is probably a good idea and here is a video that may help (although using a different LP plug-in the info applies to the LP 64)
