Haven't got Category Displays Set Up Correctly

My first problem is an inconsistency in how the categories are displayed. At the initial login, the categories are displayed as shown in file [1].

When you click on "categories" a second time the view changes to what you see in file [2].

Using links as an example, file [3] shows what you see.

File [4] shows the actual content.

My users are not going to want to dig down three-to-four levels to get to actual content. I thought what I was setting up was going to turn out like this board - a category [beginners] with the list of posts/discussions immediately after the category, as shown in file [6]

A second issue has to do with options for Facebook and others shown in file [5]. I went through the set-up options and thought I had turned them all off; obviously I messed that up. This a completely closed site - I can't have these options to post to social media. I can't open the site to users [scheduled for Wed/Thursday] with these options available.

I tried to set-up using Forums as you have, but went to categories instead. I think that was a mistake on my part.

I will appreciate any help you can offer to undo what I've done and get it done properly.

While getting my site to look like yours is #1 on priority list, getting rid of the social media options is #1.1.

I thought I'd be ready for next week, but I didn't realize how badly I had done.

Thanks

Mark
