Custom HTML inside of Tab problem

I am using this code inside of tab content inside multiple tabs, however it will only show inside of 1 tab and not the others. I have tried changing some class names but it wont work.

<div class="mcb-wrap mcb-wrap-a3440925a">

    <div class="mcb-column mcb-item column-4">

       <div class="mcb-column-inner mcb-item-icon_box_2">

           <div class="mfn-icon-box mfn-icon-box-left mfn-icon-box-center">

               <div class="icon-wrapper">

                    <img src="">

               </div>

               <div class="desc-wrapper">

                   <h4 class="title">PLACEHOLDER</h4>

               </div>

           </div>

           <ul class="mfn-list mfn-list-center mfn-list-middle">

               <li class="mfn-list-item">

                   <span class="icon-right-dir" aria-hidden="true"></span>

                   <span class="mfn-list-desc">Last Update: 01/01/2023</span>

               </li>

               <li class="mfn-list-item">

                   <span class="mfn-list-icon"><i class="icon-right-dir" aria-hidden="true"></i></span>

                   <span class="mfn-list-desc">PLACEHOLDER</span>

               </li>

           </ul>

           <div class="desc">

               <center>

                   <i class="pulse green"></i>

                   <span style="color: #4CAF50;">PLACEHOLDER</span>

               </center>

           </div>

           <div class="mcb-column-inner mcb-item-button-inner">

               <a class="button button_full_width button_size_2" href="PLACEHOLDER" title="PLACEHOLDER">

                   <span class="button_label">PLACEHOLDER</span>

               </a>

           </div>
