LACP issues

I have some 450G2 switches that I can not get LACP LAG to work on. Core 670 switch is grouping ports 19 and 20. Sh lacp lag displays:
Member Port Rx Sel Mux Actor Partner
Port Priority State Logic State Flags Port
--------------------------------------------------------------------------------
19 0 Current Selected Collect-Dist A-GSCD-- 1049
20 0 Current Selected Attached A-GS---- 2049
================================================================================
Actor Flags: A-Activity, T-Timeout, G-Aggregation, S-Synchronization
C-Collecting, D-Distributing, F-Defaulted, E-Expired

Remote switch shows:
Member Port Rx Sel Mux Actor Partner
Port Priority State Logic State Flags Port
--------------------------------------------------------------------------------
1:49 0 Current Selected Collect-Dist A-GSCD-- 1019
2:49 0 Defaulted Unselected Detached A-G---F- 0
================================================================================
Actor Flags: A-Activity, T-Timeout, G-Aggregation, S-Synchronization
C-Collecting, D-Distributing, F-Defaulted, E-Expired

I have tried moving the fiber cable to different pairs. removed and added the grouping. Disabled ports, renabled ports, all with no affect. Link lights are on both switches.

What can be wrong?

Not sure if this is a connected issue or not, but all of my network switches are also showing a loop detected on the uplink port from the core. ELRP is active on edge switches with the uplink ports excluded.
Slot-1: [CLI:vlan:2] LOOP DETECTED : 846382 transmitted, 9114521 received, ingress slot:port (1:49) egress slot:port (1:49)

Fairly new to Extreme switching so bear with me.

Hello Jason,

So the port is active and has a "y" next to both ports? on both sides?

Can't check without LACP right now while school is in session.

What version of EXOS are you using on the 450-G2's?

Hello Jason,

What does the "show sharing" display? If LACP wasn't working correctly then it should show the port as active but not added into the aggregator so it will display a "-" instead of a "y". Does it link up when you configure it without LACP? This could be a good test.
