"Disable IP range" in TCP/IP Connection settings is misleading customers

Customers who wants to configure one single IP address instead of an IP range are seduced to check "Disable IP range". But if this option is checked, not the IP range is disabled but the whole entry. There is no way to understand that checking the box disables the whole TCP configuration entry. The screenshot shows that the entered IP address 192.168.20.254 is still white and not greyed out.

P.S.: We had one customer last week having this problem and today we have again another customer that checked this option and not not get TCP/IP netTAP devices scanned until he contacted hilscher.
