Help?

So first off, thank you for this incredibly handy wizard! Second… I have an issue. I added several hosts and applied the configuration. I then realized I mis-typed the description for them all, so I deleted the hosts from Nagios XI and applied the configuration changes. Now when I go back to add all of the hosts, I get the following error for each:
IP Address or FQDN has a space: HOSTNAME

So now I can’t bulk add all of the hosts even though they don’t actually exist in the NagiosXI config.

I’m pretty new to Nagios XI, but I imagine this has something to do with the database that tracks changes before applying them to the flat .cfg files in the nagios directory? Am I close at all? How do I go about solving this predicament?

To any that provide feedback, thank you for your help!
