First:
This happens when using custom icons for custom post types, as described here: https://develop.serialdesigngroup.com/code/custom-post-type-admin-icons.
I’ve added the following to the css file for my WP admin:

.icon16.icon-post:before,
#adminmenu .menu-icon-post div.wp-menu-image:before {
	content: "" !important;
}

Note that this requires you to set icons for every custom post type, as this removes the default icon for custom post types.

Second:
The sub menu has a fixed width, which causes item labels that have long names to break out of the blue box. This can also be fixed using css:

#adminmenu .wp-submenu li a {
	overflow: hidden;
	text-overflow: ellipsis;
}

I’ve added the following javascript to add a tooltip containing the full item label’s text:

;!function ($) {
	"use strict";

	$(function () {
		$("#adminmenu .wp-submenu li a").each(function (index, element) {
			$(this).attr("title", this.innerText);
		});
	});
} (jQuery);

Good luck!

Hi Kathy,

Thank you, I’ll give it a go and let you know if it works!
