Technicians don`t show on job pages

Hello, we have problem with showing technicians on job pages after lastest update. And there is anothe  problem, the technicians can`t be deleted from the list.

Hey, To delete existing technicians 

Please go to >> Users section of WordPress here

Select technicians

And you can delete which technicians you don't need

The Field Type Author's name seems to be integrated with some other plugin, can you please try to deactivate other plugins and check which plugin is doing this. 

Otherwise kindly share your logins and explain the problem you are facing so we can help you! Thanks.
