There is a problem displaying the form in the easyblog-after-content location for each category

Let's see if I can figure out the problem with an example.
I created three blog categories and linked them to three menu items with EasyBlog typology »Layout categories» Layout category

Attached is the "SEO" configuration and I would always like to get structured urls like this:
http://Www.mysite.com/blog/alias without the category
And as I set it up, it works properly.

I have created 3 modules and I must show one for each blog category in the easyblog-after-content position and the problem is that nothing is displayed.
Before I had only one module in the easyblog-after-content location and in the module settings I had specified that it should always be displayed and appeared, now instead of creating the three menu items and in each module i will specify that it should only appear in No menu item specific for each category is displayed.

I hope I have explained

Where am I wrong?

thanks a lot
