Harvest reroll corrupted map with influence removes any influence

Hello.
I'm not sure if this is an intended behavior or a bug, so I'm writing in this section. If it's not a bug, then this is a suggestion.
I discovered that Harvest reroll corrupted map recipe completely removes any influence from a map (Shaper/Elder, Conquerors, Originator). Is that intended or a bug?
If this is intended, then there is my suggestion. It would be nice to have a way to reroll corrupted map that got unplayable mods for my build into another similar map and keep it's original influence.
Now it is somewhat dull feeling when trying to corrupt hard earned Originator map and it rolls unplayable mods and you can't do anything with it. I thought harvest reroll can help but just lost Originator influence at all.
