StoreBox - no Custom fields in Product page

Dear SIrs,

I have a small problem with VirtueMart and StoreBox.
No Custom Fileds displayed on Product page. What could be a problem?

Storebox is not Default template... Should I again to check if "url"-s and etc. are correct in such case (like in was in my topic respecting NOT displaying pop-up Cart).??
or it is a template limitation?

Other fields are OK. Only Custom Ones are missing on Product Page.

Hope to get a reply.
And Many thanks in advance for some ideas.
Andrey

One more thing - I read many post and see that it is a common problem.
I renamed file \templates\gk_storebox\html\com_virtuemart\productdetails\default.php as there was recommended many times... and
opa! everything works - customs fields are displayed !!!
What does it mean?
Problem is in your template and implementation of Product Details Page in the template.
I see many messages and replies.. And I see how despare many people with that issue.
I hope that this time there will be a luck.
VirtueMart is updated to the recent version.

Custom field not appear only if there is no class in the box layout.
If you write the class onbot or ontop they will appear.
Pending a response of gavick as to why the normal class or leaving empty not allow you to see, I hope to have helped

Just to make this clear since I had the same issue

When adding the custom field you need to add at the layout position field: ontop
