cannot open a card page from admin

[gcegithub]

Hi,
When you are clicking on the demo web site on : red_shoes_on_sale card by example,
you are using the url : http://localhost/Sandbox/grav-admin-v1.3.1/#page/product_releases/red_shoes_on_sale =>page open OK

Now, try to open from the admin panel the same page. The url turn to : http://localhost/Sandbox/grav-admin-v1.3.1/cards/product-releases/red-shoes-on-sale =>page NOT open and loading running

#page is replaced by cards
I tryed to use : Page redirect but,

pick up a link url from a post, try to open the post into a new web session, the template stays on "LOADING". You cannot expect to share an url.

How to be compliant by the admin functions and share post url?
Thx

PS/ grav-admin-v1.3.1 + std template 1.1.3
