eBGP Loop with ACI Leaf switches

Hello,
I am trying to connect Cisco ACI Leaf Switches to an external network through a Meraki MX75, but I am encountering several problems. As soon as I enable the interface going to the second Leaf switch, some sort of loop occurs and we start having a CPU spike and packet loss. Does anyone have any idea what may be happening?
Interestingly, if I add an L3 Switch in the middle, this doesn't occur.

EDIT: The MX75 is not configured with Routed-Interface (only the Leaf switches), the MX75 has each interface in a dedicated VLAN.

Kind of a big deal

The MX is in concentrator ( ONE arm )  mode ?
