Regarding Update "Apply configurations"

I have deleted host & Services from Nagios Xi -ISKVVSP01
But when we apply configuration using CCM it is showing below error..
-Error: Invalid max_check_attempts value for host 'ISKVVSP01'
Error: Could not register host (config file '/usr/local/nagios/etc/hosts/ISKVVSP01.cfg', starting on line 16)
i have already check -/usr/local/nagios/etc/hosts & /usr/local/nagios/etc/services. No ISKVVSP01.cfg file available inside this location.
