Hello ! 

Your “issue” if coming from the pagnination parameter.

If you add up the number of services by host displayed on your screenshot, you reach the defined pagination limit (30). 

So you can increase this pagination limit in order to display all your hosts. 

THANKS.
I didn't understand that in the host view it was also necessary to integrate the number of services per host.
I don't find this very logical, but it works.

Thank you for your reply.

Best regard

Bernard
