Unexpected cast shadow settings appearing twice

Step to repro:

• Open an URP project with VFX package installed
• Create VisualEffectAsset
• Create SG & enable "Support VFX Graph", save it.
• Assign this SG to VFX Output
• Observe empty "Surface Options" as expected in inspector of VFX Output
• Go back to SG and now toggle the option "Allow Material Override", save it.
• In VFX Output, observe "cast shadow" is appearing twice.

Expected:

• Cast Shadow is supposed to be hidden by the material settings

N.B.:

• Can be also reproduced directly loading attached package (compare state of two output)
• Changing any settings in material and reset it will workaround the issue
• Only reproducible in 2022.3 & 2023.1, 2023.2.0a18 introduced a new workflow where the problem is irrelevant
