Cannot Revert Charging Limit Setting

[proxis]

I’m using the most recent version of Manjaro KDE edition. I saw an option under Advanced Power Settings for setting a charging limit. I kept the upper limit at 100%, but changed the minimum threshold for when the computer starts charging while plugged in (I believe I set it around 30%). I decided I didn’t like this behavior, so I went back into the settings to change it back. However, every time I try to access that setting, it disappears. It will show up very briefly when I go to Advanced Power Settings then disappear in a flash. Is there anything I can do to fix this, or do I have to reinstall the system?

Update: In addition to the battery now refusing to charge beyond 23%, the variables /sys/class/power_supply/BAT0/charge_start_threshold and /sys/class/power_supply/BAT0/charge_stop_threshold are now set to 223%. /sys/class/power_supply/BAT0/status is “Unknown (threshold may prevent charging)”. I tried changing the thresholds with TLPUI but that seems to be getting ignored.

if it worked previously; unless you’ve removed some related packages,it may be a bug in kde and will get fixed later on.
or maybe it’s something else,idk.
here are 2 related topics that might give you hints:

While I still have the “disappearing option” issue in the KDE settings, I’ve gotten battery charging thresholds to work via the tlp gui. I installed the acpi_calls kernel module and everything seems to be working as it should.
