Hi Kinley -
Without seeing your model it's impossible to be sure. But this type of result is likely because you have changed the value of a variable in your "Ref" scenario to a value that is very different than what was written into Current Accounts. If you see the same result for many sectors, then it is likely that you have repeated this for many variables, or, you have changed the value of an Activity Level variable at a parent branch (for example, the "Household" branch itself).
Hope this helps,
Taylor
