Hi! I encountered a problem with multiselect save buttons on one of my pages. All the save buttons appear inline at the end of the first multiselect option element.

<div class="collapse" id="searchCollapse">
<form action="/users" method="GET">
  <div class="card card-body">
    <div class="row text-center">
      <div class="col-md-6">
        <%# NAME INPUT %>
        <div class="md-form">
          <input
            id="searchName"
            class="form-control"
            type="search"
            name="name"
            aria-label="Search name"
          />
          <label for="searchName">Name</label>
        </div>

        <% /*==== INPUT 1 ====*/%>
        <select class="mdb-select md-form" name="input1" multiple>
          <option value="" disabled selected>input1</option>
          <option value="option1">option1</option>
          <option value="option2">option2</option>
          <option value="Not specified">Not specified</option>
        </select>
        <button type="button" class="btn-save btn btn-primary btn-sm">Save</button>
        <div class="row">
          <%# INPUT 2 %>
          <div class="col-6">
            <select class="mdb-select md-form" name="input2" multiple>
              <option value="" disabled selected>input2</option>
              <option value="option1">option1</option>
              <option value="option2">option2</option>
              <option value="Not specified">Not specified</option>
            </select>
            <button type="button" class="btn-save btn btn-primary btn-sm">Save</button>
          </div>
          <%# INPUT 3 %>
          <div class="col-6">
            <select class="mdb-select md-form" name="input3" multiple>
              <option value="" disabled selected>input3</option>
              <option value="option1">option1</option>
              <option value="option2">option2</option>
              <option value="Not specified">Not specified</option>
            </select>
            <button type="button" class="btn-save btn btn-primary btn-sm">Save</button>
          </div>

        </div>
      </div>
      <div class="col-md-6">
        <%# INPUT4 %>
      </div>
    </div>
    <%# SUBMIT SEARCH %>
    <div class="text-center">
      <button type="submit" class="btn btn-primary buttonDefault">
        Search
      </button>
    </div>
  </div>
</form>
 </div>

As I wrote all 3 save buttons(except submit form button) get displayed on the first multiselect element(INPUT1). I'm adding a screenshot from inspect page. I'm using the same structure on another page and there it works fine. Thanks for the support!
