Based on your comments, you actually don't have a problem, it just looks like you do.
In 3d worlds, that is quite common to see, because they are so perfect that we don't see the little variations or issues that happen in real life that make things look right. Also, when you have any curved surfaces, things can get flipped around or upside down very easily.
It looks to me like the reflection of the jug is just flipped upside down. It's a bit hard to see in the image you posted, but it looks like it's reflecting off some curved glass objects, and you'll have refraction too, so there are plenty of ways that the light can bounce and bend, which gives the results you see.
It's like looking into the concave side of a spoon, or a reflection of a shiny pot that curves inward. Things just start to look a little weird when you have reflections and refraction with curved surfaces. Combine that with how 3d worlds look too perfect and you're bound to see cases where things don't look quite right, even though they physically are.
