Guarantee gone?

Hello Stinger-Freunde, I have a question about the guarantee: the start of the warranty was the 12.07.2018 I bought the car September 2023 (53,000km) with 2 years remaining guarantee. I still have 19 days to have my maintenance carried out (as of 54,500km) Today I was at Kia and the employee told me it was the big inspection due with approximately 2,500€ – 3,000€. He looked into the service booklet and told me that between entry 2 (February 2020) and entry 3 (March 2021) the Garan Since I don’t really have a lot of idea, I was shocked when he showed me that. Ask you: Was he right or did he get lost? If my first maintenance with the vehicle, previous ones took place by the previous owner. I attached pictures. Thanks and greetings, Moppelche
