Header/Footer item flickering/moving on hover

New to wordpress, here it goes.

Using Placester wordpress version 4.0.1 Theme: Toronto

In both the header and footer menu when you hover over the phone number under Contact US the item increases and decreases in size while flickering. Also in the footer under Email US.

Thanks in advance
