Okay, I'm still pretty new to Simulation so this might be a regular occurence but I've never encountered it.
I have a model of surface elements that I ran. I had to change one of the surfaces as the defining part was updated. Now the features that reference that feature have little green X's next to them. I updated the model as well as "update all components". I had to update one of the Fixtures and Pressures because their original surface was changed. They are properly defined again so it's not an error. And I remeshed and that didn't eliminate them.
They are on Fixture-2 and Pressure-3 in the image below which I highlighted. (I ran the simulation and the X's remain)
What do the green X's indicate?
