Modals

I am getting this error After the installation
Warning: Undefined property: stdClass::$position in/htdocs/cms/plugins/system/modals/src/Document.php on line 86
This one with an active link
Warning: Undefined property: stdClass::$auto_group in/htdocs/cms/plugins/system/modals/src/Link.php on line 75

the Active link seems just to load a new page

The currently installed Joomla! version is "‎4.2.6"
Plugin is 12.0.0 released today

Ok That fixed the errors but I still cannot get the modal to display it links directly to the URL. External links work but article URLs are stripped of the CSS

I have tried adding width="600" height="400" or width="80%" height="80%" But there is no modal effect


The Site Is a Helix ultima Template with SPPage Builder I have used the test modals in a normal Joomla Article

If I can get this working I will want to go pro as I would like to use the gallery effect
And also link to a HTML page containing the new Adobe acrobat embed API

Perfect thanks Will sort the styling issue with my template supplier
