If your site uses recurring items and totals are not displayed as expected then there is a possibility to replace content in

app/design/frontend/base/default/template/onestepcheckout/summary.phtml

with content available on

https://gist.github.com/speedupmate/5f8b1c20f88b0bbfcc61.

Doing this will replace OneStepCheckout custom totals display template with default rendering templates for totals and fix the display.
