Insepections not working?

After turning on the inspections for "Serializable class without "serialVersionUID" and "serialVersionUID field not declared private static final Long" I thought Intellij would tell me that my class was missing a serialVersionUID , but I do not see this warning.
Is there another step I am missing? After checking the two above in File > Settings > Inspections > Serialization Issues is there something else I must do?


Thanks for the help!
