I belive rike should be replaced with folkdom or folksdom because while rike is an accurate translation of the word state. Folkdom or Folksdom is a more accurate translation of "republic". This constitution was meant to serve as a basis for republicanism and each state is regarded as having a republican form of government. Also it says each state is regarded as it's own sovereign entity and we see today in how countries like france or the czech republic are called states but also republics like the republic of france or the czech republic. So using folkdom over rike is actually more accurate and a better philosophical translation at least.
