bootstrap-table: Duplicate headers when using tables in tabs

When I use the bootstrap table in two tabs (bootstrap tab), the header of the table in second tab is duplicating.

The code I’m using to test:

• JEC
• Cível

    <div id="resultProcessosPendentes" class="tab-content">
        <div class="tab-pane fade in active" id="jec">
            <h5>
                <small>
                    <table id="tableJEC" data-toggle="table" data-url="jec.json" data-show-columns="true"
                        data-search="true" data-show-refresh="true" data-show-export="true" data-pagination="true"
                        data-height="414">
                        <thead>
                            <tr class="white">
                                <th data-field="id" data-sortable="true">
                                    Prazo
                                </th>
                                <th data-field="name" data-sortable="true">
