Unexpected closing tag error (Mustache PHP)

The following code generates the error in the subject.

<table class="table"> <tbody> {{#deptrows}} <tr> {{#depts}} <td> <div class="form-check"> <input name="LocationDept[]" class="Departments form-check-input" type="checkbox" checked value="{{Dept}}"> <label class="form-check-label">{{Dept}}</label> </div> </td> {{/depts}} </tr> {{/deptrows}} </tbody> </table>

The mustache tag structure looks OK to me, what am I missing?
