Juniper EX Switch not seeing traffic

Little lab i have set up - Juniper MX Router - Juniper EX Switch - Cisco ASA

ASA and MZ have subinterfaces tagged for vlan 5, the EX switch has access ports in VLAN 5, but i cannot ping from MX to ASA or vice-verse. Logs on the ASA show it ARPing for the MX IP, it has a directly connected route out of the right interface, but the Juniper Switch is not showing any packets coming from the ASA when i run "monitor traffic interface xxx"

The Switch is seeing the MAC's of the MX and the ASA in its mac table but for some reason its not seeing the packets come to it. Any ideas as to what to check next?

EDIT:

The Juniper switch can see traffic on the default vlan if i do a monitor traffic (Can see VRRP packets coming from the MX router), but nothing else
