How do I get the columns in the job properties to
show the "Last Run" and "Next Run" information,
currently this columns are blank and only the column
"Next Run" has information right after I enter
scheduling information. After the job executes, this
column blanks. The log shows no errors after job
execution. I have this job scheduled to run daily.

Do you run 24x7 as a service or as a standalone program?
Does the blue count-down clock on the bottom show next job start time?
After you enter "scheduling information" do you press the Cave button?

Do you get any warning message when starting 24x7 GUI while the service is running? If yes, did you read it?

Yes I get a warning message. Does it mean that if
I'm running 24x7 as a service I will not get all the
information on the GUI?. Will the jobs still be
waiting to be executed after or during my using the
GUI? How do I know when will it be the next time a
job is to run?

Correct, the GUI in this case is just a "dumb" terminal to modify jobs, change configuration and view logs and reports.
Yes, jobs will be executed while you are working with the GUI.
You can use the Job Forecast report from the Report menu to check job execution times.
