Hi mate, It was me who had the same problem with Analog Lab and Reason.
The problem seems to be that when you open up your project again, the plugins are using the patches saved in the "concerts" part instead of your chosen patch.
To fix it I deleted all concerts, including the demo concert, so there is nothing there for it to default to.
I do remember it was a bit of a faff, needing to delete the concerts in the plugin popup within my DAW, and also delete them from the Analog Lab main application.
I recall doing this multiple times until it stuck.
If you do this without saving over your project, you should have the original patches you had previous to this error occurring.
