Hi Dwight,
For your first question you may not be able to see a formula cause that field could be a Rich Text manual entry field. It is a less used option but it allows users to add in text with the ability to use rich text styling on that text for display. You can usually tell the difference because the manual entry Rich Text gives you the Display options of number of lines, max characters, and width of input box while the formula version only gives you a max character option since there isn't an input box. They both show up as just Rich Text in the type.
You can turn log editing on in a Rich text field but it usually isn't on by design. With the field type adjusting on you it might be that the template app had that enabled and adding Gantt caused it to start logging. If things aren't woking right for you when you have plug ins turned on and are using Gantt I would recommend putting in a case with our tech support team to get some help trouble shooting. You can create a case here in Community using Support where it appears in the navigation at the very top of the page or in Quickbase when signed in under the question mark (?) icon by selecting Manage Support Cases.
