Not a habanero

I grow chillies every year. In 2021 I bought a young plant that was labelled as a Habanero. It didn't produce a single fruit. I nearly composted it but decided to give it another try, so over-wintered it indoors. This year was quite different. It went outside in June, and produced loads of white flowers, then these fruit. It's back indoors now that the weather is cooling off, and it's still producing flowers.
The thing is, whatever these are, they're not habaneros, which are normally a completely different shape. The chillies are very hot and all this shape with a slight dimple along the side. The fruit have no seeds, unlike the other chilli varieties I grow. 
Any idea what this might be?
