SLA - Not displaying First Response by and Resolution by fields after all set up

Hello,

I have created one SLA with Basic Service Schedule of business hours Mon-Fri from 9.30 AM to 6.30 PM.

SLA is activated and set as default.

Now, when I have created a case, not applied any entitlement. So that it considers default SLA.

It is showing Timer on Enhanced SLA Details section. But it is not displaying First Response by and Resolution By fields.

I have followed this link:

Do  we need to setup anything else except this?

Thank you,
