MultiCheckBox missing

[minecraft2048]

I'm not sure how to check installed Pluto/PlutoUI version, these are my imported packages:

begin
    using Geodesy
    using SatelliteToolbox
    using Dates
    using TimeZones
    using StaticArrays
    using JuMP 
    import Ipopt  
    using Geodesy
    using EAGO
    import NLopt
    using SatelliteToolbox
    using StructArrays
    using LinearAlgebra
    using PlutoUI
end

Hey @minecraft2048 ! Can you send us an HMTL export of the notebook? You can use gist.github.com to upload and share the file.
