Hi, we are experiencing some issues when installing the app eCommerce, when it is installed the following error appears:

Error while validating view: Element '' cannot be located in parent view

It seems that the app is installed after a page refresh, also on the website it looks all just fine, but if we try to upgrade the module we have this error:
