After upgrade from F-Secure Client Security 13 to version 14, the Powershell function "get-wmiobject Win32_Product" was still returning information for the old Client Security 13 version.
An upgrade to the sidegrade module was released on Febuary 4th, 2020 (version 12.43391.52). This fixed the issue with the upgrade not removing the MSI-registration data. If you have installed F-Secure Client Security 14 before the release of the upgraded sidegrade module, a reinstallation of the product will solve the issue.
