Error when web site is not in root folder

Hi,

My server has two web sites

First one is in the folder : site-1
The second one is in folder : site-2

to access this web sites I use

https://server/site-1 or https://server/site-2

When I edit a web page with SP Page Builder Pro and save and close
the return url is wrong, and site-1 or site-2 is missing

https://server/index.php?option=com_sppagebuilder&view=dashboard&tmpl=component

How can I resolve this ?

Thanks for your help
