Creation of the Certificate deletes the Watermark image from pix folder on the server

[LukeMyAs]

In Moodle 3.8+ (Build: 20191220) fresh install - mariadb 10.3.15, Php 7.3, Apache 2.2 - opening the "Certificate" link in the course
https://mymoodlewebsite/mod/certificate/view.php?id=32
that uses an image, deletes that image from the corresponding /pix directory.

I changed the Certificate type, the folder (watermarks instead of borders), I deactivated the "Save certificates" and changed the Delivery, but nothing changed.
