Conflicting IVR menus

I have two IVR menus in my dialplan which I seem to have set up incorrectly. If the second number is dialed (2224) and a selection is made (1 or 2) the action is always routed through the first number's (2230) sequence.

So for example, when I dial 2240 and select option 2, 2232 is executed instead of 2242.

Can anyone spot the problem? Part of extensions.conf pasted below:

Thanks for looking.
