Running Signed Scripts Remotely

I have a PSADT deployment that is signed. Deploy-Application.ps1, AppDeployToolkitExtensions.ps1, AppDeployTookithelp,ps1, and AppDeployToolitMail.ps1 are all signed in my 3rd party certificate.

It works great on my machine. I copied the file to a remote machine, opened a remote session (Enter-PSSession) and executed it. I was notified, in turn, that each of these scripts was signed with my certificate, and that my certificate was not trusted on the system. I checked the remote computer’s TrustedPublishers store, and it looks like everything is in place.

Is this normal when running the script remotely? Or do I have a problem?
