Left and right Y axis with same units

Hello.

Grafana docker: Grafana v8.0.6 (68fe9e3431)
Host OS: Ubuntu 20.04.2 LTS (GNU/Linux 5.4.0-80-generic x86_64)

I have two queries, both working. One returns less data, and the other a lot of data. If I have only left Y axis, the less data is almost invisible at the bottom, that is why I want to make use of the right axis as well. However, if I use the same units ( Misc → Short ), only left axis is not shown.

I have recreated it at play.grafana.com, but I cannot save it.

Best regards.
