PATH environment variable appears as "Path" in agent parameters

Hello,

I am having a problem on some of our blades where the PATH enviroment variable is spelt "Path" in "Agent Parameters/Environment Variables". For example if I get the list of environment variables on a blade I get:

If I then check environment variables in TeamCity I get:


This issue with PATH being spelt "Path" only happens on some agents. This difference in casing makes it impossible to setup agent requirements as some agents will work with env.Path and other env.PATH.
I tried restarting the agent and the machine and it didn't work.

Does anyone have any idea of how this could be fixed?

Thank you,

Clem
