They will slowly come down on their own as long as you aren't dosing them or doing water changes with a high Ca/Mg mix.

The only way to bring them down manually is to do water changes with a lower Ca/Mg salt. Some salt mixes are high. Which are you using? And are you measuring salinity with a refractometer calibrated with a saltwater standard?

They are fine, especially the calcium.

That said, I would not dose any magnesium to this system, if you are confident in the test (not all are accurate)..
