The purpose of language is to communicate. If they use the wrong terms and communicate, it's not an issue. If they use the wrong terms and miscommunicate, that is an issue. If they are miscommunicating, you can always ask them what they mean when they use the term, and say it's because you want to make sure you understand what they are saying, and you've heard the term used in a different context and want to make sure you and they are on the same page.
