In my preset for (at least) interlaced Iris model the program always returns to Dione DV despite saving i.e. applying saved preset in new input requires to change the model from Dione to Iris every time. All other modifications are saved/shown correctly. This happens in newest 5.3.3 release but was in older versions as well (had no time to report but it`s annoying). My system: up-to-date Windows 11, Ryzen 7900 and RTX 4070 Super.
The team is still investigating what is causing the the app to swap out the models and reset them to Dione DV even in saved presets.
Hopefully they will have a resolution soon and get it into an upcoming patch update.
