I see the problem but do not know what is causing it. What I did to fix it was to insert two more rows just below the MX 860 Printer then reinsert the IP data by hand (copy & paste the remaining data). Appeared to be a fix.

I noticed that when you look at the IPs after turning on the Pilcrow there were dots underlining the IPs. Don't know why the dots were there but when taking them away (by typing in the IPs rather than copy & paste)...it worked.

Hope this helps...
