Easy accordion does not choose id

I have a page with only [eaf_items id="2932"]on it and as you see on https://varosvedo.hu/cvarosvedo-csoportok/ it shows all my Accordion items I have in the Admin. This is not my purpose. If I put several items with different id-s on the page, it displays the whole store of items again and again. Now I purchased the Easy Accordion Pro, hopefully I get support there, but there is not any link to the author. I should like to know if i get the same error using that plugin, before i begin to work again with the items. They are not herited from the free version. Please, help me. Or please, give me the contact to the special support of Easy Accordion Pro.
