Option 43 and missing options

Hello,
I'm running DHCP Server 4.3.3. I have implemented option 43 to hand out the
URI of a tr069 server in the network.
It works. However, when I am successfully giving a lease with option 43
added, I am not getting options 3, 6, and 28. The lines I'm adding to my
subnet statement are:
shared-network Internet {
subnet xx.xxx.xxx.0 netmask 255.255.255.0 {
append dhcp-parameter-request-list 43;
option vendor-encapsulated-options
01:xx:68:74:74:xx:3a:2f:2f:xx:69:6e:65:70:6f:xx:6e:74:2e:73:77:xx:79:7a:65:65:2e:63:6f:6d:3a:38:30:38:35;
option routers xx.xxx.xxx.254;
option broadcast-address xx.xxx.xxx.255;
range xx.xxx.xxx.50 xx.xxx.xxx.254;
]
A dhcpdump of a lease offer with option 43 (notice it's just plain missing
the routers, dns resolvers, and broadcast options.

If I remove the "append dhcp-parameter-request-list" and the "option
vendor-encapsulated-options" lines, I get a complete lease and all is
well...unless I need option 43 to be sent....which of course I do.
I've tried moving those two lines to be underneath the "range" line
(reaching, I know), to no avail.
Has anyone experienced this before?
Regards,
Ryan Gray
