This Werk fixes a regression that occurs since Checkmk 2.4.0.

At the Printer cartridge levels ruleset, you can enable the option Upturn supply levels (Previously called Upturn toner levels) to fix values from a device that reports its levels in an unusual way. This fix, while being effective for Containers like ink cartridges and toners, failed to apply for receptacles like waste boxes.

Alongside this Werk, the wording around the Upturn supply levels option and the Check's manpage has been adapted slightly to clarify the scope and meaning of this feature.
