Logically if IH2 was the cause you would truly have issues with more than just two categories.. A quick look at the IH2 code and you would see that it is indeed category neutral.. I suggest having a go at some of the troubleshooting options suggested in the article nagelkruid posted..
Thanks guys for all your help, but I've found the problem. It looks like one or two products in each category referred to a image file that wasn't on the server in the corresponding folder. Once I've uploaded the file and updated the products, they are now showing up as they should.

So, thanks guys for trying to help me. I just wanted you to know I found the solution and what was it.

Cheers!
