Intellij IDEA Inspection background color not appearing for certain warnings -


currently experiencing issue background color have set warnings shows on warnings.

screenshot

the inspections/warnings line 19 show background color correctly in addition orange line on right gutter.

however, inspection unused parameter only displays in right gutter, not highlight. doesn't seem make sense both warnings , don't seem controlled separate styles in color & fonts > general > errors , warnings.

any ideas? tried loading pycharm profile (where works expected) no avail.
