for example, item for field "store value" has id/name "delta" in directly attached item, but becomes "delta_name" in a templated item.
while this might be because the field is not editable anymore, the same principle is not applied to all fields - for example, "name" field doesn't have it's id/name changed.

this sometimes breaks automated tests, so it should be figured out why is it done this way and documented in the guidelines
