Excel section reports is not working in the apps that I created

Hi!

I have install the Excel reports builder from the Marketplace (https://marketplace.creatio.com/app/excel-reports-builder-creatio) and I have the following problem, when I want to generate a new section report for one of the new sections that I created it doesn't show the button that allows me to download the report. I have this problem with the sections that I created using the Application Hub and with the Accounts and Contacts section because I try with other sections like Activity and it shows the button to generate the report. 

Any help greatly appreciated here. 

Thanks you.
