Ul List text out of line only on ios

As per title.
If you go here & then hover over Accessories you will see that the drop down list text is fine.
This is the same for all the drop down lists on the pc http://www.theremotedoctor.co.uk/index.html

Having said that when looking on an ios device its to the right.
Looking at the screen shot below shows this.

Making the 2 padding figures the same sorted this out.
Original seetings were 40/15 but now both 15/15

Code:

---

.srt-menu li a {
        background:#66C2F1; /* background header option accessories etc colour before selecting ios */
        display:block;
        margin:0px 0;
        text-align:center;
        padding:15px;
        text-decoration:none;
        border: 2px solid #000000;
}
.srt-menu li li a {
        background:#FFFFFF;
        padding-left:15px;
