Some placeholders have no output + add rounded placeholders or output rounded values about iridiumskyblock

does this also happen when setting the number formatter in settings?

configuration.yml

numberFormatter:
  numberAbbreviationDecimalPlaces: 2

Yes, I have set the settings as you described. The BUG described above in the display of decimal places still exists.
Even changing the value to 1 or 0 does not change anything.
My current attitude is:

configuration.yml

numberFormatter:
  numberAbbreviationDecimalPlaces: 2
  thousandAbbreviation: "K"
  millionAbbreviation: "M"
  billionAbbreviation: "B"
  trillionAbbreviation: "T"
  displayNumberAbbreviations: true

As a test, I used the placeholders in another plugin, "DecentHolograms", to check whether the incorrect output was due to the scoreboard plugin.
Unfortunately, "DecentHolograms" displays the values with the same result.
