Execute If within a For Each

I'm doing a project using: Php, css, html, mariadb "mysql"

I am trying to execute an If statement within a ForEach loop, but the "if" only executes in the first execution of the Foreach, in the rest everything is executed, except for the If. I do not understand what's happening.

Here my code:

As you can see, I have some rows and columns to show: first: an identifier, second: general information of the corresponding identifier third: in a progress bar I show certain information. fourth: I execute an if to determine what kind of information to show in another progress bar. fifth: I show two dates

This image shows how all the results should look: This image shows that the second progress bar is not loaded in all results.

Here my code:

<?php
                foreach ($records as $r) {
                    $p = 100 - $r->PT;
                    ?>
                    <li class="list-group-item">
                        <div class="row">
                            <div class="col-md-1 text-center">

                            </div>
                            <div class="col-md-4">
