Please look at menu submenu

Hi there,

i have recently updated wordpress etc..

My menu seems to have changed.
I am using a child theme.

Will you please visit the site and see what I need to change to widen my submenu links out again.
They have become way too narrow.

Also here is what i have in quick css:
This is what was there before but is possible i have something wrong anyway.
.logo {
visibility: hidden !important;
}

#top #header .mega_menu_title a { font-size: 12px;}

#top #header .avia_mega_div > .sub-menu.avia_mega_hr {
padding-top: 5px; }
#top #header .avia_mega_div > .sub-menu {
padding: 5px 10px 10px; }

.main_menu ul:first-child > li > a{
padding: 0 6px !important;
}

.main_menu ul:first-child>li>a {
font-size: 12px;
}

.sub-menu{
padding-top: 1px !important;
padding-bottom: 1px !important;
}
.sub-menu li > a {
font-size: 14px !important;
padding-top: 0 !important;
padding-bottom: 0 !important;
}
.avia_mega_div .avia-bullet{
margin-top: 1px;
}

#top #header .mega_menu_title a {
font-size: 12px !important;
line-height: .8em !important;
min-height: 15px;
}

#header .mega_menu_title {
font-weight: 500 !important;
}

End

Thank you
