MutiSelect Component Error in Console

[neovia-ciro]

Hi There,

I am using MutiSelect Component as below:

            <MultiSelect
                inputId="diretor"
                value={selectedVigencia.listaDiretores}
                options={usuarios}
                onChange={(e) => {updateData(e.value, 'listaDiretores')}}
                optionLabel="nome"
                placeholder="Escolha"
                display="chip"
                maxSelectedLabels={3}
                filter
                required 
                className="md:col-9"
                // pt={{
                //     label: {}
                // }}  
            />

When I look at console developer tools, there is the following warnings:
Warning: Encountered two children with the same key, null. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version. Error Component Stack
at div ()

Warning: Encountered two children with the same key, 0. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version. Error Component Stack
at div ()

Warning: Encountered two children with the same key, 1. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version. Error Component Stack

They appear twice times, for each selected value, beside that, is appearing a null label in the DOM.

I red the following post but it solution doesn't help me.
