If you altered them via ID Resolver, you do have to go into the actual config. for this add-on and give those numbers ID Resolve assigned to blocks/items.. Because (unfortunately) ID resolve won't alter text based config.s, and That's where the add-on pulls its slot ID dedications from...
I do not use ID Resolver. If I run into a problem, I either remove the mod zip or roll back to my last Minecraft.jar, depending on how I installed it, and then look through TMI's list for openings I can manually assign the new blocks to.
It might be slightly archaic, but at least I know what is going on, and it prevents fragmentation of mod items.
