I have added a block to appear in the Content region, however it appears above the content of the node for French, but below the content of the node for English - which is strange as (as far as I know) they're both the same content type and should be the exact same templates.

Although the block name (and /url) is the same as the English nodes' url so maybe that's causing some problems which causes the block to appear after the nodes' content?

Is there any way to specifically define that you want a block to appear after the nodes' content? i.e. through weighting inside the module that adds the block?

EDIT: I've set the weighting on the blocks admin page, it's +15 for the block and the Main Page Content is -17. I also dragged it out of that region then back (without saving) before saving but still appears above for the French node and below for the English node...
