Scheduler Not displaying all jobs in dropdown

After updating to 7.10.9, I no longer see the list of jobs in the schedulers module.

Is this due to the latest update? Where would be the best place to loo to correct this issue? I have tried replacing the Schedulers Module with a default copy. Also checked the _AddJobsHere.php, which is populated.

Any suggestions would be much appreciated.

This is a known issue, will be fixed in 7.10.10.

You can look for the fix from there, and apply it manually, if you need it immediately.
