Being the original contributor is irrelevant to the question of removing a death and burial.
To remove the burial information, go to "your" Ezra's detail page (https://www.familysearch.org/tree/person/details/L2DN-7HZ) and click "Edit" next to Burial (in the Vitals box). On the resulting pop-up window, click the "Delete" link at the bottom right. Enter a reason, then click the red button.
To remove death information, click "Edit" next to Death in the Vitals box, click in the date or place field, then use your keyboard's backspace or delete keys to remove the information. Once the date and place fields (and their associated reason boxes) are empty, click the blue Save button at the bottom left.

You DO NOT "Edit" that Record 'per se' ...
Use the "Delete" link/button, on the Bottom 'right-hand-side' (ie. on that "Image" of yours), while in "Edit".
That resets the "Burial" record to the "Default" (ie. NOTHING).
For those trying to follow along who are still confused: the main source of Don's problem is the difference between the "Death" field and the "Burial" field.
Most fields under Vitals are optional: you can have a profile with no birth, christening, or burial. But if there is a birth, christening, or burial, it can't be blank. To get rid of the vital, you have to delete it, not blank it. This is achieved using the "delete" link at the bottom right of the Edit popup for the vital in question.
The death field and the name field, on the other hand, are non-optional, so they have no "delete" link in the bottom right corner. They also cannot be entirely blank, but for the death field, this just means that the "deceased" radio button has to be selected. Therefore, if you know a death event is incorrect, but have no correct replacement, you need to blank it.
The mobile app concept is the same but it works a little differently; there are little "x" delete buttons at the right sides of the fields in the Edit tools.
And this is a topic for Q&A.
