Job title different than TN profession

Im currently on a TN as a dietitian and have had one in the past both have been titled registered dietitian. I am now a certified diabetes educator and looking to apply for a new TN under dietitian. Im wondering if its an issue that the job title is diabetes educator and not dietitian? The job requires a dietitian background providing diabetes education. Ive also checked dietitian under the Occupational Outlook Handbook and they mention that we can get specialized and work with only patients with diabetes for example. Wondering if there will be an issue with the title is different than the direct name of the TN category " dietitian"
