Hello,

Now we checked and now discovered the reason.

1. You added the icon “ambulance” via Appearance > Menu and at the same time, you have an icon in the category. That is why you had two icons. So, you can apply an icon either in the menu or in the category, but not both at the same time.

2. You renamed an existing category in the menu instead of adding it. That is why when you change the icon in the category, nothing changes, cause in the menu you have another category.

Best Regards
