Page-Problem CC7

Hello,

I have a form on the page in CC7:
/index.php/my-area/my-observation-overview
On this page there are various data records in a table, each of which is linked to a processing form.
If I click on a link, I can edit this specific data set in the edit form. For example:
/index.php/component/chronoforms7/?chronoform=observation overview&gpage=view&article_id=260057

The forms work but I have the problem that the edit form is in a Joomla page layout that doesn't match the layout of the CC7 page.
In the backend of CC7 I have a standelone
Page group: connection
Page:2 name: index (here is my overview table)
/index.php/my-area/my-observation-overview

Page:3 name: view (here is the editing form)
/index.php/component/chronoforms7/?chronoform=observation overview&gpage=view&article_id=260057

In CC6 this was never a problem. What happened? What should I do?

F.

Problem solved.
Probably no one understood what my question meant.
For everybody who's interested:
If I want to link a CF7 form page to another CF7 form page, this can be a possibility:
Text node with text content
Interface: link
Page/URL: {url:index.php}
Parameter:
gpage / cf7 form page name

or for example with redirect:
URL: ?gprage=CF7 Forms Page Name
