Trailhead SuperBadge: Lightning Experience Reports and Dashboard Specialist; Day 1

In my training for Salesforce Administrator, I am currently working on one of my SuperBadges as a form of studying for the certification exam. The project is testing the potential administrator on how to making a custom picklist object, import data, link folders in the object with specific permissions for specific users to each folder, as well as creating public groups for the users. I created a new playground to help me with the project and so that previous settings to previous playgrounds do not interfere with current playground. Then, I created my custom picklist object and imported the data (reports) in that object. Next, each public group for the object was created and named by department in preparation for their respective permissions. After creating the folders for each department and inserting the respective reports in the right folder, I assigned access and permission (view, edit, manage) to each folder. The public group assigned, determined the access or control that the user obtained. So, I had an error when I went to check my work. Trailhead said that the object that I created was not found. Two issues might be causing this error alert: one is that I deleted a folder that was supposed to be placed in the Recycle folder, or two that I created the wrong record type.
