Custom bypass effects not working?

[LogicSequence]

I've created a new bypass type (i.e. gateway) and set its ftl_ship_effect and ftl_bypass_effect to new effects; however, no matter what i change, the vanilla effects are what get triggered. Is this a bug or am i doing something wrong? I've even left the fields blank and it still uses the vanilla effects.

new_gate = {
    name = NEW_GATE_GALACTIC
    is_pathfind = yes
    uses_action = no
    requires_exploration = no
    always_active = no
    windup_time = 0
    winddown_time = 0
    ftl_multiplier = 0
    icon_frame = 30
    remember_instances = no
    galactic_map_tooltip_header = NEW_GATE_GALACTIC
    galactic_map_tooltip_desc = NEW_GATE_GALACTIC_DESC
    connection_type = scripted_connection
    animation_time = 1
    ftl_ship_effect = "new_gate_ftl_ship_effect_entity"            #<--- This is ignored?
    ftl_bypass_effect = "new_gate_ftl_bypass_effect_entity"       #<--- This is ignored?

    country_can_use = {
        custom_tooltip = {
            fail_text = "NEW_GATE_DISABLED"
            NOT = { has_global_flag = disable_new_gates }
        }
    }
   
    scripted_connection = {
        node = { has_star_flag = new_gate_origin }
        nexus = { has_star_flag = new_gate_destination }
    }
}
