LACP Frames / Level3 Transport

Hi Nanog-ers,
Hoping someone may have come across a similar issue. Has anyone ever seen a situation where maybe like a Level3 transport system could be possibly dropping LACP frames..?
End point A -? tx and rx counts incrementing for LACP

End Point B - no RX, partner macs are 0s..

Link works fine otherwise outside the aggregate and w/o LACP. Any inputs will be greatly appreciated.
