Hi,
Action Plan:
1.you can create a new user profile, lock it, and perform the same action to see if the problem is still there.
2.If the same issue exists for the newly created user, please uninstall and reinstalled the steadystate to test out. Please understand it it recommend to uninstall Shared Toolkit before install SteadyState per the steadystate handbook.
3. If the same issue exist after step2, the problem can be related to the fact the public profile is not successfully locked. For this situation, you can refer to this thread: Locking User Account .
