It sounds to me like you have two different sets of standards in each tracker. Formative assessments depend on the actual standards on the tracker. So you can manually add the correct standards to your current tracker and then add the assessment. This will leave two sets of standards in the tracker, however.
Benchmark assessments are distributed based on the standards that the tracker was created from. So if you have benchmark testing, the central office would have to manually add the benchmark to your tracker.
It may be easier to archive the tracker and create a new one based on the correct set of standards.
