Aren't you seeing the variable? It depends on the report suites selected. The variable should be enabled and its classification created in all the report suites selected. There is an additional factor too. Let's say you have enabled evar1 for classification in Report Suite A and B, however, you have named it as X in A and Y in B. It will just be showing up as X - and if you select that, it will classify evar1 in both A and B.
