2 DHCP servers and PfSense DHCP server won't lease

Wim

First of all don't shoot me, I'm a network newbie. However, I googled around for hours and tried various things… all without result.
I hope someone can help here and tell me how to get it working.

The challenge:
DHCP on my Pfsense does not lease IP adresses and gives an error (see below).

I have a cablemodem/router from my ISP.
--> DHCP cannot be turned off.
--> Address 192.168.0.1, and leasing IP's for the full range 192.168.0.2 - 192.168.0.255 (which cannot be changed)
--> no control on firewall or any other thing, except port forwarding
My goal is to use PfSense as a router right after this one, also with DHCP/NAT turned on (I know I know, double NAT is not great). However, I want more control.
--> 2 interfaces defined, WAN & LAN
--> WAN is set to DHCP, all settings as default
--> LAN is set to Static IPv4 with address 192.168.1.1
--> DHCP server is turned on:

Subnet
192.168.1.0
Subnet mask
255.255.255.0
Available range
192.168.1.1 - 192.168.1.254
Lease Range set from 192.168.1.10 to 192.168.1.50

This setup just doesn't work... and the weird things is also: I'm receiving an IP address of 192.168.1.100 when connecting a pc on the LAN side ... also Internet works.

Error log DHCP server shows:

It is fixed… by updating PfSense to the latest release. I thought I already had the latest since I only did the setup yesterday.
It seems there was an issue somehow in that version with DHCP...

...and now I get an IP lease of 192.168.1.10 - which is what I expected:-)

Current version now is:
2.3.2-RELEASE-p1 (amd64)
built on Tue Sep 27 12:13:07 CDT 2016
FreeBSD 10.3-RELEASE-p9

The system is on the latest version.
