So I tried a bunch of different things to get the address right. If I put a constant on the block diagram, the right address showed up in the drop down list, but when I selected it, it displayed as "all" instead of "All". I tried dragging the address from the project, same story, it said "All" in the project, but "all" when I put it on the block diagram. Not every channel had this behavoir though. I have an AO-200 in the same back plane, it worked fine. I ended up just going into MAX, and changing the name "All" to "0-7", or however many channels I had on that module as a work around, which seems to work. It would still be interesting to find out what caused it.
