BibTeX, biblatex and biber ⇒ Citations show only first three Letters of Author Name

[Asatorae]

Hi there,

it's driving me crazy. I'm using a custom template on ShareLaTeX.

I'm trying to do citations with BibTeX, but when I try to use the alpha bibliography style and then \cite{key} in the text, it only gives me the first three letters of the author and some of the year in the citation. E.g. \cite{Smith} outputs "[Smi11]".

Any help?
