for more details on the issue: when we create a monthly subscription the dates are from say Feb 1 to Mar 1. and those flow through to the rev elements and arrangements fine. But when we renew a subscription we find that the existing element end date gets updated to Apr 1. so everything kinda gets updated as if it was a two month subscription from Feb 1 to Apr 1 instead of the wanted behavior of having a new arrangement for the renewal of Mar 1 to Apr 1.
