I'm using CSVI Pro 7.7.0 with Joomla 3.8.11 an these problems occur on two different testservers/installs.
My main problem is shown in this screenshot, the contents in the maintenance list are not displayed
If I get redirected from the "install example templates" link (that is shown in the green message if you have now templates) i can see them.
My second problem is, that I can't find the option to "Use ICEcat data", like mentioned on this support page

The files index and the manufacturer index are loaded...
