Job Scheduling Options on Job Entry

We are testing Kinetic 2021.1.8 and are moving from 10.2.400 to it this weekend. We are on prem.

We have come across an issue with Kinetic screen in Job Entry. On creating a job and releasing it, Job Scheduling options slid out panel opens up. Normally in 10.2 and also per manual in K21.1 we should be able to select between forward and backward and pick a time. However, all the options are greyed out.
See the screen below. Has anyone else come across this issue.
