My guru categories are showing a 404 error, even when they are all published via the guru categories menu, also you can notice that when the 404 error is shown, my main menu won't show instead you can see an ijoomla link on the main menu position that will direct me to the student registration page.

2 of them are also published via main menu these are "profesional y negocios" and "crecimiento personal"

the "instructor" category works fine, but the others doesn't; "instructor" category was the ijoomla category precreated on guru installation

you can also notice that on the left side there are two modules that are showing the guru categories menu, but as you can see, they only show 2 categories when in fact i have created an published 25 categories.

that is the guru categories layout, if you click on any category but "instructor" you will receive a 404 error

if you click on the two categories created on the main menu, they will show but not correctly

as you can see, it is not showing the category image, even when that same image is showing on the categories layout.

could you please guide me on how to fix this issue?
