NUT app - Multiple UPS Debian 11

I recently configured LibreNMS using docker-compose in my home server, using the compose example in GitHub - librenms/docker: LibreNMS Docker image
Then, I configured two Raspberry Pi (Debian 11) with NUT, one with a single UPS and another with two connected by USB.

I followed some guides and everything worked perfectly, I was able to monitor the three UPS and check them in the NUT GUI with no issue.

Finally, in order to have everything in just one place, I followed the guide in Applications - LibreNMS Docs
But despite implying that you can configure multiple UPS with the given script, on the raspberry that I have with two UPS, it only shows one.

Is there a configuration that I’m missing? Or something to consider?
