Challenge Not yet complete... here's what's wrong: 
The Suggestion custom object does not contain the correct set of custom fields. Tip: check for typos in the field names.

Hello,

I am currently running in to an issue on Step 6 of the Lightning Experience Rollout Specialist Superbadge.

When I click check challenge, this is the error I get:
Challenge Not yet complete... here's what's wrong: 
The All Lusso Scarpe Employee group page must display the following information on the right side of the page: recommended groups and individuals to follow, and the most popular topics currently under discussion.

Here is a screenshot of my page:


Can anyone help me understand what I am doing wrong?

Thank you!

I am facing another issue on this superbadge, specifically in Challenge #10, i am getting the following error:
The Campaign Influence Lightning report must have the correct 1. Aggregate, 2. Columns, 3. Groupings, and 4. Filter.

The requirements have no mention about what fields, groupings, filters, aggregates to include in the report. What am I missing?
