White space being added to email sections

I've noticed that whenever I edit an editable email section in my template using the editor, <p><br /></p> is added at the bottom of my HTML. For example, if I put in:

<table class="one-column" style="background-color: #ffffff;" width="100%" bgcolor="#FFFFFF" border="0" cellpadding="0" cellspacing="0">
      <tr>
         <td style="text-align: center;">
            <table style="border-spacing: 0;" width="100%" border="0" cellpadding="0" cellspacing="0">
                  <tr>
                     <td class="text" style="font-family: Helvetica, 'Helvetica Neue', Geneva, Verdana, Arial, Tahoma, sans-serif; color: #333333; ;font-size: 14px; mso-line-height-rule: exactly; line-height: 19px; text-align: left; padding: 25px 15px 15px 15px;"><span style="font-size: 16px; font-weight: 600;">Do you have the real-time visibility you need to deliver the best quality products to your customers?</span><br />Frameworks and tooling around agile and DevOps have evolved to help, but value streams still go dark during the last mile of software delivery as ideas get converted into digital bytes. As we continue to scale agile across our enterprises, the ability to manage value streams from idea to end-user is becoming a critical requirement.</td>
                  </tr>
              </table>
         </td>
      </tr>
</table>

it gets changed to:

<table class="one-column" style="background-color: #ffffff;" width="100%" bgcolor="#FFFFFF" border="0" cellpadding="0" cellspacing="0">
      <tr>
         <td style="text-align: center;">
            <table style="border-spacing: 0;" width="100%" border="0" cellpadding="0" cellspacing="0">
                  <tr>
<td class="text" style="font-family: Helvetica, 'Helvetica Neue', Geneva, Verdana, Arial, Tahoma, sans-serif; color: #333333; ;font-size: 14px; mso-line-height-rule: exactly; line-height: 19px; text-align: left; padding: 25px 15px 15px 15px;"><span style="font-size: 16px; font-weight: 600;">Do you have the real-time visibility you need to deliver the best quality products to your customers?</span><br />Frameworks and tooling around agile and DevOps have evolved to help, but value streams still go dark during the last mile of software delivery as ideas get converted into digital bytes.

                  </tr>

<p><br /></p>

This added HTML is causing unwanted gaps in the email design.  Has anyone else experienced this, and is there a way to avoid it?

I've attached my email template.

Thanks in advance for any help.
