CS6 Master Collection perpetual license – orphaned activation cannot be deactivated

I legally own a perpetual Adobe Creative Suite 6 Master Collection license.

The Adobe activation server reports that my serial number is already activated
on two computers. In reality, I currently have access to only one activated
computer. The second activation belongs to an old system/computer that no
longer exists, so it is impossible for me to deactivate it locally.

My Adobe account shows no activated devices, which is expected because remote
device deactivation is only supported for Creative Cloud applications.

I am not asking for technical support for an unsupported CS6 application.
I am asking Adobe to correct/reset an orphaned server-side activation record
for a perpetual license that I purchased.

Could an Adobe employee please escalate this to the licensing/activation team?

I can provide the serial number and proof of purchase privately if required.
