ran a california contractors license lookup before signing and something didn’t add up

A family friend recommended a contractor she swore by for a home addition project. Nice guy, showed up on time for the consultation, quote seemed reasonable. Before committing to anything, my wife ran a california contractors license lookup on him through the CSLB site, just to confirm everything was current. His license was technically active. What caught her eye is that the business name on the license didn't match the LLC name on his business card or his proposal. Different entity entirely. When she dug further, the LLC printed on the card had been dissolved six months ago?? We asked him about it at the next meeting and he got flustered, said he was "switching over" paperwork. That might be completely true but like I've been around long enough to know that vague explanations deserve follow up questions. Has anyone here run into this exact thing? Is an entity name mismatch a genuine problem or do contractors do this routinely and it's not really a concern?
