Problem with pgadmin4 : displaying data in the query editor

Hello,

I installed "pgadmin4" (version 4.20 for Window 10 64 bits). With this app,
I connect without worry to the PostgreSQL database that I installed on a
virtual machine (PostgreSQL 11 and VM under Debian 10 installed in
VirtualBox).

But although I can visualize the data contained in my PostgreSQL database
from Windows with Putty or with Qgis (for geolocated data), I can't
visualize them with "pgadmin4" in the query editor .

In the query editor of "pgadmin4", when I make a "SELECT" query, the "Data"
tab returns nothing.
However on the "message" tab I have a message telling me that the request
has been executed. Here is a message for one of my tables: "Successful
execution. Total time: 574 msec. 2780 lines affected.".
Also under pgadmin4, the other SQL commands work well (create, insert,
update, delete ....)

Previously, I was using pgadmin III and I didn't have this problem. I went
around the parameters of "pgadmin4" and looked on the web, but I did not
find anything to solve this problem.

Does anyone can help me ?

Thank you.
