U-HE confirmed the bug, it's reproducible and simpler than first encountered. The first instance of Presswerk get recalled correctly on load but all the rest not. In steps: 1. Save FX Chain with Presswerk in it (HQ Mode on) 2. New empty project 3. Load Chain -> everything fine. HQ Mode on. 4. Load Chain again -> HQ Mode off, labelling went away Same for Track Templates and Projects with several Presswerks in it. No other parameters are changed.
