Hi Andy,
You can try to add a new position named top-panel for this JA Nex template by opening file: templatesja_nextemplateDetails.xml
add this line of code:
<position>top-panel</position>
inside <position> tag
<positions>
<position>right</position>
<position>accordion</position>
................................................
<position>top-panel</position>
</positions>
then go to backend settings of JA Top Panel module and assign it to this new position.
Note that you may also style a bit for it as by default, this module is not included in this template.
Regards
