Drupal – Block and Views content not Showing on the page template

I have created the following regions:

homeslider: 'Home Slider`
homecontent: 'Home Content'

The regions appearing in block layout and I can assign any block on them. However when I create a block with any content type and add it to any region nothing appearing, while when I add a block with basic title and body it’s working fine! 
Could you advice on this issue?

Drupal version:
