Apply ACL to VLAN Interface

    I created a lab using ContainerLab following 'AOS-CX Switch Simulator Lab - ACLs' and everything works without issue. I am now attempting to change the uplink from SwitchA to SwitchB from layer 3 to layer 2 and and applying the ACL to the VLAN interface instead of the physical interface. The ACL does not get applied properly (I can still ping from the devices) if I run 'show access-list commands' I receive the following: 

    ! access-list ip ACL-IPV4-1 user configuration does not match active configuration.
    ! run 'access-list TYPE NAME reset' or 'access-list all reset' to reset the ACL to match the active configuration.

    I have looked around here and read through the release notes for the switch simulator, but I cannot find anything that says apply ACLs to a VLAN interface is not supported.

    Any suggestions would be greatly appreciated!
