Problem when updating variation price

Hi,

So everything works great, until I change the price on a variation and say update. As soon as I do that my products go all out of whack and they no longer display correctly on my site. Instead of showing the grouped product it shows the variations and no picture.

How can I prevent this? I need to hand over this site to my client and need this to work before I can hand it over.

thanks in advance for your help
