help with getting an object to show (change to normal state) when all buttons are visited

There are several things you may want to consider.

You grouped a text box and a rectangle. then add a trigger to each of the items. Groups don't play nicely with anything, but especially not with triggers and states.  Your triggers are already written for the individual elements, so at the very least, you don't need the group. I would also get rid of the text box, and just place the test on the rectangle. One object, one trigger; simpler things work better in SL.

The real problem, though is the Hidden and Disabled states you have created. If an object is in a hidden state, SL makes it invisible. By creating your own Hidden state, you have interfered with that normal function. You were fortunate to get away with it on the disappearing text box, but it caused a corruption in the appearing text box. You need to edit the states of all those objects, and delete both the Hidden and Disabled states. Then you need to delete the 7 CTA 2 box and recreate it.
