Trouble Setting Up Aggregation on My Ubiquiti Switch

Hey everyone, I'm really struggling with getting my Ubiquiti 8-port SFP 10GB aggregation switch configured properly. I've got it connected to a UCG fibre gateway and an 18-port Pro Max switch, and I'm using a Proxmox cluster along with a VMware cluster for my three hosts. All hosts have 2x10gb SFP modules and I've set ports 3/4, 5/6, and 7/8 to aggregate, but they just aren't working.

I configured the bond on Proxmox as LACP203.ad with layer 3/4 filtering on the hosts, and all network ports are set to VLAN ID 9. The issue is that once I try to aggregate, the ports show as offline. I have an additional NIC on the hosts using vmbr0 for other VLANs, but setting a static address on the bond VLAN hasn't resolved anything.

I aim to establish three bonds for the hosts, mainly for Ceph traffic, and avoid mixing it with management or VM network access, but I've read that the switch might not support three aggregation links. Even testing with just one link has failed. I didn't configure a gateway address for the bond VLAN since it's isolated without internet access. ChatGPT hasn't helped much as it mentions seeing more options in the Ubiquiti interface for aggregation settings, but I'm not finding those. Could the issue stem from the OS limitations of the UCG fibre compared to Unifi OS?
