Scan range always resets

AngryIP is one of the best utilities I ever saw. My compliments to the chefs.

I apologize if I'm the zillionth one to ask this, but I hadn't noticed it before.
My IP network goes from 192.168.86.1 to 192.668.86.255

When I launch AngryIP, it always presents me with 10.6.6.202 to 10.6.6.202

Not a huge range. ;) . And it certainly isn't my range. All my preferences are stored and used. The IP range, not so much.

MacOS 10.13.4
ipscan 3.5.2 (x86_64)
java 9.0.4+11
