Managing elements to avoid duplicates

I'm fairly new to Telerik, so bear with me.  I'm wondering if someone can provide some advice on how to best manage the elements feature.  When beginning to build out my test suite, I first went through the target website and created elements for any items that are global or reused on multiple pages and named them with "friendly" names for reference.  However, I'm finding that as I build out my test suite, elements are automatically added using the default name it pulls from the source code.  What I end up with is a bunch of elements with vague/ambiguous names and it's a somewhat arduous task to go through and identify and rename them.  Also it appears that some may be duplicates or at least target various portions of existing elements.  What are the conditions in which an element will be auto generated?  This might help me to understand how to handle. 

Thanks in advance.
