System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 536.99

Blender Version
Broken: version: 3.6.2, branch: blender-v3.6-release, commit date: 2023-08-16 16:43, hash: e53e55951e7a
Worked: 3.6.1

Short description of error
The Vertex Weights Panel appears to be broken in 3.6.2

Exact steps for others to reproduce the error

In the attached .blend file, select a vertex in Edit Mode
In Object Data Properties, go to the Vertex Groups Panel and set a weight with the Weight slider
Use the 'Assign' to execute the bpy.ops.object.vertex_group_assign() operator, assigning a weight to the selected vertices
In the Item > Vertex Weights panel, if there are multiple Vertex Groups, the same weight will be displayed for all the vertex groups.
Either open the Spreadsheet Editor to see the correct weights or run the below script in the Text Editor to print them in the System Console. You will see that the Item > Vertex Weights panel is incorrect.

import bpy

context = bpy.context
active_obj = context.active_object
previous_mode = context.object.mode
bpy.ops.object.mode_set(mode="OBJECT")

if active_obj.type == 'MESH':
    vertices = active_obj.data.vertices

    for vi,vert in enumerate(vertices):
        if vert.select:
            print("#"*20,vi,"#"*20)
            weights = [g.weight for g in vert.groups]
            for i,w in enumerate(weights):
                print(i,w)
            total_weight = sum(weights)
            print("total_weight",total_weight)

bpy.ops.object.mode_set(mode=previous_mode)
