In the above places you have trailing dots on "arpa" but not on "be". 
That might not be the issue, but it is worth checking.

|id |domain_id|kind                |content        |

|5  |10       |TSIG-ALLOW-DNSUPDATE|dhcpdupdate    |
|7  |15       |TSIG-ALLOW-DNSUPDATE|dhcpdupdate    |
|9  |10       |ALLOW-DNSUPDATE-FROM|127.0.0.0/8    |

These aren't consistent, but since zone 15 is working, zone 10 should be 
OK. In any case, you can use tcpdump to check what is the source address 
of the DDNS update packets (and should also decode their contents)

tcpdump -ilo -s0 -nnv port 53
