Authentication error on my own element?

I have an application that creates elements based on a template.  In some cases, after the element is created, an analysis expression needs to be modified that can't be done at the template level.  For example, my element template has a simple analysis template baked in that simply has a "No Operation" sort of result.  However, in some cases, the user decides that a specific element really does need an expression to be evaluated and thus provides an expression.  That expression is then applied to the analysis for that specific element.  Take a look at the following link if you're interested in a previous discussion on how that is achieved:


Can the AF Analysis engine evaluate strings?


The actual problem arises when I am creating an element.  I have granted the user permissions to read/write elements.  I have granted the user permissions to read/write in the database.  I have granted the user permissions to read/write analyses.  However, despite that, when I attempt to create an element and then modify the analysis within that element, I get the following error:


System.Security.SecurityException: Cannot complete the operation because the user does not have rights to delete Analysis 'Is OON (EF)' with UniqueID '7230e7b6-5c71-11e5-9e90-005056a56372'.

Does anyone have any ideas how to get past this?  It's a blocking issue for me at the moment.
