Separation Mode / Shifts state not saved in user preset of OpenVINO Music Separation.

As somebody who makes Radio Edits, I've decided it'd be useful to create macros to have 2 Stem and 4 Stem OpenVINO Music Separation available at a keypress (bound to NUMPAD0 and NUMPAD_DECIMAL), I set up the macros by first creating a User Preset for both, and in testing those buttons, I've found a major issue, both the state of the Separation Mode (2 Stem or 4 Stem), and the number inputted into Shifts are not saved in a user preset. Instead, creating a preset is effectively meaningless and pointless, as it just resorts to whatever the last settings were and not the settings you've inputting

Start by locating the OpenVINO Music Separation user-preset serialization and the settings for Separation Mode and Shifts. Reproduce the issue by saving separate 2 Stem and 4 Stem presets with different Shifts values, then reload each preset. Done means both settings are restored from the selected preset rather than the previous values.
