On d9b05eb490a the way aliases containing a mix of IP address and FQDNs works has changed and all items were added to filterdns to make sure the pf table created would be persistent. The flag $use_filterdns was being set only when the array item used to control didn't exist yet. Because of that, the second call to the same function made it to return a different result. Set it independent if a new array item is created or not to make the function to properly return the right thing.
