It need to solve without changing other options

The way those colorful numbers work in WordPress is that the number is technically part of the menu title. So if you change the title, the number will disappear. In theory, you could manually add the HTML code that displays the number to the menu title, but then it would just show the same number all of the time.

If you had the Pro version of the plugin, you could probably work around the problem by adding the [ame-count-bubble] shortcode to the menu title. This shortcode copies the number HTML from the old title to the new title.

However, the free version doesn’t support shortcodes. I don’t think there’s an easy way to change the menu title without changing or removing the number.
