Failed to place several lists on the same page

Muchas gracias por su valioso trabajo.

Thank you very much for your valuable work.
These days I’m doing some tests, including groups and fields in lists.

But to try to put a list under another separated by a container div or other shows me only half the site, the rest is blank.

Example:

List of people in Germany
[pdb_list filter="country=Germany"]
List of people in Portugal
[pdb_list filter="country=Portugal"]
