SXT 5HPnD r2 Wireless mode reverting

Hi there,

This is my first Mikrotik environment so still getting used to it. I have a two receivers (SXT 5HPnD r2) and one sender (SXT SA5). One of the receivers is communicating perfectly with the sender and makes a good strong connection.
However, with the same settings on the next receiver, I struggle to make a connection. When I set the mode of the wireless interface to ‘Station wds’ and then connect to the Sender via the ‘Scan’ button, it reverts back to the mode ‘Station’.

Here is my current configuration:

[admin@Reciever 2] > export
# jan/02/1970 00:06:09 by RouterOS 6.30.2
# software id = IILX-U92F
#
/interface bridge
add name=bridge1
/interface wireless
set [ find default-name=wlan1 ] disabled=no l2mtu=1600 mode=station-wds ssid=\
    MikroTik-Test wds-default-bridge=bridge1 wds-mode=dynamic-mesh
/interface wireless nstreme
set wlan1 enable-nstreme=yes
/interface wireless security-profiles
set [ find default=yes ] supplicant-identity=MikroTik
/interface bridge port
add bridge=bridge1 interface=ether1
add bridge=bridge1 interface=wlan1
/ip address
add address=172.16.252.2/16 interface=bridge1 network=172.16.0.0
/system identity
set name="Reciever 2"
/system leds
set 0 interface=wlan1
/tool romon port
add

From reading the logs also, I get this:
mac address@wlan1: failed to connect, on 5180000, medium-access timeout
