Dell G3 3590 not obeying charge intervals

Hi,
My Dell laptop (G3 3590) does not obey charge limits set in the BIOS, both manually, as well as using smbios (or /sys/class/power_supply/ entries) I can confirm that the charging mode is set to custom.

I am really not sure but I think it used to work a little better a few kernel versions prior

Whenever the system is run on AC power when the battery should not be charging according to the settings, it works as expected for a moment and then starts charging regardless.
I can confirm via smbios and the relevant  /sys/class/power_supply/ that the  charging  mode and intervals are set correctly..

The charging intervals also seem to reset after reboots

I have the nvidia driver disabled for the moment (though having it enabled caused very finicky behavior if I recall correctly)
