tried this solution. it does not work. the method i have described above, simply viewing the item, solves the problem. i am interested in this problem because it is strange, and as a beginner, it really throws you off.
You can try closing your project, going to the directory (right clicking on the project in the EpicGameLauncher you can do this quickly) and remove the entire directories Saved / Intermediate / Build (not all might be present) then launch the project again and make sure you give it some time to rebuild things like shaders and other indexes.
I was able to reproduce this issue on our end. I have written up a report (UE-22612) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.
