System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 416.34

Blender Version
Broken: version: 2.80 (sub 75), branch: master, commit date: 2019-07-29 14:47, hash: f6cb5f5449
Worked: (optional)

Short description of error
[Shape keyes break when created with the X-Mirror enabled. Any new blank shape key added will already have information when turned to '1.00' when it shouldn't]

Exact steps for others to reproduce the error
[Add a shape key > change shape key value to "1.00" > enter edit mode > turn on X-Mirror and proportional editing with connected "on" > manipulate the geometry (I did move and scale) > add a driver for that shape key > create a custom property from the object tab and have it update the shape key > in the driver editor create a new var and remove it > change the name of your vars > update dependencies > change the name back > update dependencies > now your shape key driver works fine but when adding a new shape key, it'll behave as if it already has information already when turned to 1.00{F7656776} ]
[Based on the default startup or an attached .blend file (as simple as possible)]

Similar to #67185 (Shape Keys Behaving Like a Duplicate of Previous Key ), I assume there have been modeling modifications on the mesh after adding the shapekey(s) that changed vertex count / topology?
(Suzannes eyes look like you've tried getting rid of the triangle fan...)

This only has limited support and can lead to some issues, see the above report as well as https://blender.stackexchange.com/questions/19296/can-i-fix-broken-shape-keys-after-editing-basis.

That being said, you can fix this in you case by:

open your file
select Suzanne object
enter editmode
select all vertices
select the Basis shapekey
from the menus, execute Vertex > Blend from Shape

If I do this, I can create a new shapekey that doesnt seem like a duplicate of the other shapekey...

Will merge this into #67185 [which has been closed for now because it is working as intended (even though this could be improved upon...)]
