Change is disabled but the error that it resolves is enabled

[reprogrammer]

I started applying the changes proposed for the jolden project from the top of the tree.

Change field bodyTab to @Nullable Body is marked as applied but its parent error bodyTab = null is not marked as resolved.

Similarly, Change field next to @Nullable Body is marked as fixed while its corresponding error next = null is not marked as resolved.
