The Loupedeck 5.0 software contains new types of profiles, in the streaming category this means that they have been merged into the regular system profiles.When updating from 4.3 to 5.0 the OBS Studio and Streamlabs profiles that were used are converted to system profiles. In order to access the profiles click the profile dropdown menu and then the "..." to browse the system profiles.
When the menu is open you can find your 4.3 streaming profiles in the system menu.
