I am assuming you used the same identity to start again. Since you wiped data you are at risk of being disqualified once a satellite comes looking for one of the missing pieces. As this node was only three weeks old, I suggest you create and sign a new identity and consider this a completely new node.
Out of curiosity, what did you use to edit the config.yaml file when you added the line for zksync?
