Hi bule,
Indeed, it is our tiny mistake. We do include the breadcrumb position in templateDetails.xml file while we don’t define this position on the block. Anyways, you can try to put below codes into the blocks you want in templates/ja_fixel/tpls/blocks/.
<!-- Breadcrumbs -->
<nav class="wrap t3-breadcrumbs<?php $this->_c('breadcrumbs') ?>">
<div class="container">
<jdoc:include type="modules" name="<?php $this->_p('breadcrumbs') ?>" />
</div>
</nav>
<!-- // Breadcrumbs -->
Then go to Module Manager to create a Breadcrumbs module at breadcrumbs position.
i.e I intend to put the codes into footer block (footer.php), the result will be:
