an array is a "container" for elements of the same type. These elements share all the same settings except the data they contain. Therefore, caption, description, size, color and so on will always be the same for all array-elements. You can try this as well with boolean or numeric controls.
If you want different captions for your elements, you have to place them into a cluster (not array) and after that, you can convert the cluster to an array in the blockdiagram via the "cluster to array"-function found in the clusterpalette.
