Description (partial)

some addresses are not assigned from the local pool even though the ASA shows them as available addresses

ASA configured with "ip local pool" with a mask smaller than the number of addresses configured
i.e ip local pool test mask and will be available in the ASA but will not actually get assigned because the mask breaks 192.168.0.x into subnets with usable addresses, is actually a broadcast address for the first subnet, and is the network address for the next subnet so end devices will not accept it as a usable address.
