I've been working with Delmia to study the posture of a mannikin in a work enviornment from an stl file. Somehow, when moving the mannikin around and using attachments, parts of the stl were moved. To remedy this, we imported a new copy of the stl into the original product that is reflected in the manufacturing cell. After doing this, I have been getting the following error when trying to switch simulation states: 

When I go to the Links and Relations command, I'm not sure how to remedy the status with the errors:

There are options to delete the components, to do an automatic reconnection, or a manual connection. I don't understand how to remedy the status, what needs to be done to fix the connections? I'm okay with deleting the attachments and restarting I'm just not sure that's what's needed!
