Unsupported attribute type “DURATION”

Hello, 

After upgrading to the new version of A360 (v.39), it is not possible to create new processes. Each bot reports the issue: “Unsupported attribute type ‘DURATION’.” in the Queue timeout section.

This occurs both with previously created processes and when I try to create a new process.

I have searched through the settings to find a solution, but I haven't been able to find anything. The only option seems to be switching to the legacy editor.

Is there any solution to resolve this issue?
