If you cannot see your User Patches/Presets, please ensure that they are properly organized within your STEAM folder. Click to find your STEAM folder.
Each User folder must be organized into sub-folders that contain Patches/Presets in order for them to appear inside of the instrument.
...STEAM/ Omnisphere/ Settings Library/ Patches/ User/ Synth Keys
...STEAM/ Omnisphere/ Settings Library/ Presets/ User/ Arpeggiator
Note: The User Presets folder is already organized with sub-folders to match the various Preset categories.
Once you have organized your Patches/Presets into sub-folders be sure to refresh the Patch Browser using the Refresh button at the bottom, denoted by the circular arrow.
