Quicken Deluxe Program Update Issue

We are currently running Quicken Deluxe for Windows, R31.5, Build Within the last few days, we are seeing this anomaly. When OSU is activated, the One Step Update Settings screen indicates a program update is available for download. Upon clicking the "View Update" button, a new window appears telling us "Latest version already installed." We have seen at least one reference on this forum indicating there is a more recent release identified as R31.8. Is anyone else experiencing this issue? What is the correct most recent version? Must I contact support?
