I have a project with several classes. I create the most of the icons of the methods of those classes using the ctrl+k shortcut from the quick drop. Multiple times now I had the problem that I open the project and the icons of some (not all!) classes are blank and I have to manually redo all the icons.
It happens so sporadically that I haven't found a pattern and I don't know how to recreate the issue. But I hope that someone does. I'm using LabVIEW 2021 32bit (without SP1).
