HQ Site think the traffic is local due to subnet differences?

Hi,
I work in an ISP environment and in it I found developed MPLS delivering ip
vpns.
There is one client with 5 branches.
All work fine except for 1.
This is the scenario.
The default route is derived from the corporate office (HQ). Its network
range is 172.16.0.0/16
Say branch with problem is branch Z ip range is 172.16.7.0/24
>From Z Lan I can ping HQ Lan ok
ping 172.16.1.1 source 172.16.7.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.1.1, timeout is 2 seconds:
Packet sent with a source address of 172.16.7.1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 24/29/36 ms
>From HQ I cannot ping Z apart from reaching the Z router.the lan
ping 172.16.7.1
PING 172.16.7.1 (172.16.7.1) 56(84) bytes of data.
64 bytes from 172.16.7.1: icmp_seq=0 ttl=253 time=19.8 ms
Any other connections are dropped from branch Z router
A trace reveals packets are dropped from the main MPLS PE router.
The PE router can reach the CE router but not any pc behind it.
Your input appreciated
Regards
Rocker
