Respectfully, the usability bug here is different: EPA/EPG only uses the
customized value, while the log message only uses the actual value in
the variable. So the log messages should be adjusted, if you want to
keep using the customized value only in EPA/EPG. And perhaps they should
catch and mention the case where the customized value is not the same as
the variable value, again for usability's sake.
