Label views starting at letter 'E'

When I make a drawing for a new part, I select my template then insert a view but when I do a section or detail view the label is always set to the letter E instead of A.

It's as though A-D are already used up in my template. Is there a way to change this without completely remaking my drawing template? I have been refining it over a few years.

Thanks,

Aaron.
