Those options are grayed because you're on the Recently Viewed list view instead of Angels or whatever. You have to click on Recently Viewed (upper left) and select whichever list view you want to edit and then those options will be clickable and not grayed.

Yeah, when you deleted the old Pitch object, that deleted the tab. But the new Pitch object, the one from Max's Pitch Package, came with it's own tab. Now you just have to add that tab back to the Marketing app. That's the steps right after you installed the package back in 1b. Do those to get the tab into the app. Then you should be able to resume where you left off in 2a.

It looks like maybe you are using the old Pitch object you made in Lab 1a instead of the new one that got put in as part of installing Max's Pitch Package. In Steps 1-4 of Lab 1a you were supposed to delete the old Pitch object from 1a so that you wouldn't get confused and use the wrong one. You should delete it now and then connect Meeting to the right one that will be left from Max's Pitch Package.

But if you have already added the Pitch field to your Meeting object to connect Meeting to the wrong PItch object, you'll need to delete that field, and then click on Deleted Fields and then Erase it so it's completely gone before Salesforce will let you delete the old Pitch object that you've attached Meeting to.
