Troubleshooting Work Email Waterfall Domain Mismatch Issues

Getting a bug with the Work Email waterfall for certain providers. The person's name, LinkedIn profile, company name, and company domain/LinkedIn URL all indicate one company (in this case, Expedia), but the email returned by Findymail has @morganstanley.com as the domain. How could this be happening?! If others have this issue, how do you handle double-checking for a domain match and "resuming" the rest of the waterfall if there's a mismatch?
