Use of Hostname for Network Rules does not Work (v3.0.16.295 x32)

If I apply a host name for the source address in either global or application rules, the IP associated with the host name is still blocked. An example of this is ftp.drweb.com.

An Nslookup for the host results as follows:

Name: rr.drweb.com
Addresses: 87.242.72.150, 209.160.33.73, 81.176.67.170, 81.176.67.171
83.102.130.174, 83.102.130.178
Aliases: ftp.drweb.com

If I use the host name, 81.176.67.171 is blocked. My alternative is to add each IPAddr or use Any for the source address. Host Name would fit the bill nicely, but none of the associated IPAddrs are being allowed.
