Picture on article details page?

We purchased and have the Article plugin installed here: http://absoluteessential-nop.vps3.netpotential.co.nz/articles

It all works well, but on the Blog Detail page, the main image which was uploaded is pixelated. Example: http://absoluteessential-nop.vps3.netpotential.co.nz/give-your-environment-a-health-boost-with-our-premium-quality-ultrasonic-ceramic-diffuser

image.png


Upon inspecting the image source we see that it is referencing this image: http://absoluteessential-nop.vps3.netpotential.co.nz/images/thumbs/0000344_give-your-environment-a-health-boost-with-our-premium-quality-ultrasonic-ceramic-diffuser_200.jpeg

Instead of this one which is the correct one: http://absoluteessential-nop.vps3.netpotential.co.nz/images/thumbs/0000344_give-your-environment-a-health-boost-with-our-premium-quality-ultrasonic-ceramic-diffuser_936.jpeg

Please advise what we can do to fix this.
