This is a bug in ScummVM, it works properly in the original:

The relevant script is me2j.scr

If I understand correctly, this is the script that draws the lever. At least in my case, I should add, since I didn't use the savegame provided with this bug report.

puzzle:09536 {  # me2j_setup_lever
    criteria {
        [09526] = 1 # me2j_screenset
        [09484] > 7 # me2j_lever_control
        [09484] < 11    # me2j_lever_control
    }
    results {
        action:animplay:09537(me2ja151.rlf 480 247 551 310 8 8 1 0 0 0 0)   # me2j_setup_lever_anim
    }
    flags {
        once_per_inst
    }
}

I think this is the script that decides to show a close-up of the time tunnel (where the lever should not be visible) instead of showing the control panel (where the lever should be visible). So something about this should ensure that the lever isn't shown, perhaps?

puzzle:09526 {  # me2j_screenset
    criteria {
        [09491] = 3 # me2j_guard_state
        [09419] = 1 # me2j_fence_is_down
        [09404] = 1 # me2j_time_tunnel_open
    }
    results {
        action:set_screen(me2jf111.tga)
