Hi,
For the first question answer you used UPPERCASE in css that's why its always n UPPERCASE.
Fo the second question answer is below:
Use this custom css
.sp-megamenu-parent .sp-dropdown li.sp-menu-item > a {
position: relative !important;
bottom: 14px !important;
}
Add this css code inside the custom.css file.
Note: Path towards custom CSS:
Extensions>Templates>Styles>
Click on your current default template name then choose Template Options.
Then find custom CSS within the custom code.
