building multiple SlimSelect objects in a loop - only last object works

Question

I am trying to build a html list with each item in the list having a SlimSelect object with a multiple select dropdown. However, when i run the code below, only the last item is active... the other items do not work. I am not sure why this is happening. Any advice would be appreciated!

Here are the console logs for getElementbyId

<select id="selector-0" multiple="" tabindex="-1" data-ssid="ss-74017" style="display: none;">

                                <option value="four">four</option>
                            </select>
<select id="selector-1" multiple="" tabindex="-1" data-ssid="ss-56902" style="display: none;">

                                <option value="four">four</option>
                            </select>
<select id="selector-3" multiple="" tabindex="-1" data-ssid="ss-49140" style="display: none;">
                                <option value="one">one</option>
                                <option value="two">two</option>
                                <option value="three">three</option>

                                <option value="one">one</option>
                                <option value="two">two</option>
                                <option value="three">three</option>
                                <option value="four">four</option>
                            </select>
<select id="selector-5" multiple="" tabindex="-1" data-ssid="ss-38661" style="display: none;">
                                <option value="one">one</option>
                                <option value="two">two</option>
                                <option value="three">three</option>
                                <option value="four">four</option>
                            </select>

May you share what happens if you log the result of the getElementById call? — evolutionxbox, Oct 10 '20 at 23:42
@evolutionxbox, I've updated the above to include the console.log call and the results. — Jason Guettler, Oct 11 '20 at 00:01

It seems to have an issue adding the placeholder to the select elements within the same while loop. I moved it outside the while loop into another while loop and it seems to have fixed the issue.
