Bug with a bonus from mutagens - is there a way to solve it? (The Witcher 3: Wild Hunt)

Maybe there is a mod to fix mutagens? Really already got this bug, when after a reboot you have to re-arrange the mutagens in the cells, otherwise the bonus goes only to the base one, i.e. on a large, for example, red mutagen, the bonus with 3 pumped and active skills of the school of combat, the bonus is not + 40%, but much less. Or here are the signs - I insert a large blue mutagen, writes that + 43% to the power of the signs, and after a reboot it shows + 33%, i.e. there is a loss.
