Initial preset on material creation is "Custom"

[Dragorn421]

Using OoT here, probably same for others
Blender 4.0.2 (which is most likely unrelated)

When creating a material, the preset shown is "Custom" instead of "OoT Shaded Solid", which was the value up until now

Fresh blend, fresh object and just freshly created material:

Though the preset shown is "Custom" it does seem the material is set up like "OoT Shaded Solid"

Bug introduced by #201 based on intuition and then testing before/after:
