Knockdown ability range not affecting all abilities

[probablynotval]

As the title says, knockdown's ability range stat doesnt give the boost to all abilities (except for some characters like paige and victor)
It seemingly affects all items normally, however for healing nova it doesnt display that it increases its range while still actually providing the buff
Some examples:

Just to add, knockdown does not add any range to all of Hollidays abilities, only some. Pictures demonstrate that divine barrier increases all of Hollidays abilities, however knockdown only increases a select few. Cheers
