Minecraft Scoreboard-revision Plugin is not working properly?

Hi, I've been trying to get Scoreboard-r running for two days, but it does not show me any exact stats, for example.

Player:% player_name%

Ping:

Uptime: f

I use the spigot version 1.12.2

You can find the plugin here:

https://www.spigotmc.org/...ard.14754/

You also have to use this plugin.

It would also be useful to read the description of the plugins

I have the plugin
I have already created a server only with Scoreboard r and PlacholderAPI still did not work

if you have placeholderAPI downloaded run /papi ecloud download Player, /papi ecloud download Server and then /papi reload
