First time user and *not* off to a great start :-(

Hi,
I’m not a programmer and have just installed Wappler v2.3.5.

Trying to follow the tutorial https://www.youtube.com/watch?v=fTHshWOgCcU&t=28sto create my first bootstrap page.

So I created my first project, added the bootstrap 4 and the appConnect frameworks, and now I’m working on my first page, trying to put a header.

The video says that clicking on the blue plus sign in the middle of the page or the plus sign in the App Structure panel s/b equivalent. That’s not what I see.

Clicking the blue plus sign in the middle of my page opens a menu of components but there are no option for headers in it --there’s a menu option for footers, though.

Clicking on the plus sign in the App Structure panel has a “Header” icon under “Suggested” and also under “Layout” (albeit with different icons in each).
That said, clicking on either of them does not open the secondary menu shown in the video, with options for logo to the left, centered, logo and menu, etc. When I click on the Header icon, a blank header is inserted in the page.

So, what happened with the other options?
Am I doing something wrong?

Many thanks for your help,

Alex
