I'm playing around with researches at the moment just as a bit of a practice. I'm currently implementing researches from the Vasari and Advent into the TEC tree research tree. Of course, they're not actually attached to any ships or anything yet - I'm just trying to get the them to appear properly on the tree.

Anyway, I'm trying to add a second block to the Defence tree, currently that section of code looks like this:

    Defense
        blockCount 2
        block
            area [ 50 , 93 , 690 , 235 ]
            backdrop "ResearchScreenBlockBackdropDefense0Tech"
            tierIndicatorBackdrop "ResearchScreenBlockTierIndicatorDefense0Tech"
            title "IDSResearchScreenBlockTitleDefense0Tech"
            picture "ResearchScreenBlockPictureDefense0Tech"
        block
            area [ 50 , 338 , 690 , 235 ]
            backdrop "ResearchScreenBlockBackdropNonCombat2Tech"
            tierIndicatorBackdrop "ResearchScreenBlockTierIndicatorNonCombat2Tech"
            title "IDSResearchScreenBlockTitleDefense1Tech"
            picture "ResearchScreenBlockPictureNonCombat2Tech"

So, the second block appears 10 pixels under the first and is just as large, uses the image and backdrops from third culture block and has its own name which I've also defined in English.str.

Right now I have three researches in there all of which take up the second block, the code looks like this for the first research:

block 1
    pos [ 0 , 1 ]

With [0 , 2 ] and [ 0 , 3 ] for the next two researches.

The problem is that the second block doesn't appear at all, and neither do the researches. The researches appeared before when I only had one block, so I don't think they're the problem. I can't identify anything wrong in the lines defining the block either. Is the defense tab only limited to one block, and does this go for the diplomacy tab too?
