Hello @Adam_Weissman and welcome to the forum.
Please make sure you run the latest package from here: Synology DSM7 – RoonOnNAS
Maybe also watch the install video there. If you uninstall the current version of the package and then install the newest one (may both be the same version), the installer script should run again and ask you where the music is and fix the access rights for that location. The installer also shows you a message how to give Roon rights to access other/additional folders if you need that. Make a screenshot from these instruction for future reference.
You can find instructions to fix the Model Name displayed in the thread below:
From another Roon user in hope it helps.
