In most cases, your work search isn't invalid but you might be missing key information needed to verify your search. For instance, online job applications often lack contact name(s) and number(s). If this the problem, you will need to be thorough by inputting a filler such as, "Non-Applicable" or "Unavailable" in these fields.
Furthermore, be sure to manually select the fields you need to complete. Some claimants have "tabbed" through questions rather than clicking the answer field to input information. This often poses roadblocks as it has made a contact email field required.
