Tried to see if I could replicate your problem.
Here is Address, Breadcrumb, & Search > Breadcrumb > Basic > Normal > Active Crumbs with an Arial 22pt font:
Here's the same thing but I changed the Content Margins to (2, 2, -9, -3) at Address, Breadcrumb, & Search > Address > AddressBand > Basic > AddressBand > Background:
So looks like changing the content margins at the address band might solve your problem
