1.7 I am missing TONS of modules in back office

[Bewitching]

Fresh install of ver 1.7.6.7. on a domain I use strictly for testing purposes. I am familiar with Prestashop. I have a store running 1.6xx and want to replace it with ver 1.7, hence the testing.

Under module manager there are a few native modules installed, but only in the "theme modules" and "other" category. (I am logged into the addon's marketplace on the back-end, so that's not an issue.)
NONE of the other categories' modules are installed.
Going to the Module catalog, there are only 6 modules available to me, none of which I need, and ZERO available/showing in the needed categories. ie: admin, payment, shipping etc
Looking at the attached images you can see what I mean.

I went online to the Prestashop demo to see if that's the norm, meaning Prestashop 1.7 comes "barebones" with very few modules, and everything is available on the demo site's back-end module catalog.

Help! Do I need to got to github to find the missing modules and download? Without a list of modules I'm not even sure what I need or what I'm missing :)

Thanks!

Today, I logged out of addons marketplace and viola, all the modules appear in manager and catalog.

Strange, right? When I am logged in, the modules disappear!

Makes no sense, but it's working and that's all I care about

Thanks for this hint, had similar effect with ps 1.7.7.4

Same here. Did anyone find how to fix this? The problem is that you can't upgrade a module that actually needs a connexion to Addons...
