Change version or reinstall
One process for both. World, plugins and configuration stay; you choose the Java version along with it.

What happens
Reinstall under Settings installs your template's server software again, with a version from the list below it. Stable versions and pre-releases are listed separately, and the recommended one is marked. If you pick nothing, the recommended version is installed.
The software files are replaced. Your world and your files stay where they are.
That is why there is no separate "change version" button: going from 1.21.4 to 1.21.8 and repairing a broken server file are the same process on the node.
Java
Older Minecraft versions need older Java, newer ones newer Java. Under Java version you pick the major version or leave it As before; the list of Minecraft versions below adjusts accordingly.
The server has to be off
Reinstalling only works while the server is stopped; if it is running, the page offers Stop server. Before it starts, a dialog asks again and names the version. The server then shows Installing and stays stopped afterwards until you start it. Only the owner of the server may reinstall.
Change template
You do not switch from Paper to Fabric or from Vanilla to Forge via Reinstall: the template is fixed there. Order a new server with the other template and move the world over via backup or SFTP. Plugins and mods are not interchangeable between loaders.
If something does not work, send a ticket with the name of the server.
